<p>Franco: /* Schedule */</p> <hr /> <div>David Hill from Australian National University will be visiting Caltech on 4-5 Dec (Thu-Fri).<br /> <br /> === Schedule ===<br /> <br /> 4 Dec (Thu)<br /> * 7:30 am - breakfast with Richard<br /> * 8:45 am - Francisco/Sawyer<br /> * 9:30 am - Ufuk/Nok<br /> * 10:15 am - Elisa/ Ophelia?<br /> * 10:45 am - seminar prep<br /> * 11:00 am - Seminar, 114 Steele<br /> * 12:00 pm - Lunch with CDS faculty<br /> * 1:30 pm - open<br /> * 2:15 pm - Steven Low<br /> * 3:00 pm - Shuo/Andrea<br /> * 3:45 pm - open<br /> <br /> 5 Dec (Fri)<br /> * Appointments on request (send e-mail to Richard)<br /> * 1:30 pm - Mani Chandy<br /> <br /> === Seminar Abstract ===<br /> &lt;center&gt;<br /> '''Feedback Networks'''<br /> <br /> David J Hill&lt;br&gt;<br /> Federation Fellow&lt;br&gt;<br /> Research School of Information Sciences and Engineering&lt;br&gt;<br /> The Australian National University (ANU)<br /> &lt;/center&gt;<br /> The field of systems and control has gone through stages based around focus on <br /> preferred models for systems and appropriate structures for controllers, including linear systems and state variable feedback, time-varying parametric systems and adaptive control, nonlinear systems and optimal control and so on. However, important control tasks in living systems and modern infrastructure technology actually take the form of systems with network structure controlled by distributed control, with switching, time-delays and other complexities, i.e. control of <br /> networks by networks or feedback networks. Examples in engineering include power grids, road traffic control and Internet congestion control. This model opens up a plethora of new systems and control science questions, which are being studied by separate communities in science and engineering. <br /> <br /> This seminar will describe recent work in this area mainly focussing on work in the Lab for Networks and Control at ANU. The emphasis is on the role of structure, i.e. the various graphs in the networks (system, sensing and controller), stability-related questions and self-organising mechanisms for control.<br /> <br /> === Biography ===<br /> David J Hill received the BE and BSc degrees from the University of Queensland, Australia, in 1972 and 1974, respectively. He received the PhD degree in Electrical Engineering from the University of Newcastle, Australia, in 1976. He is currently a Professor and Australian Research Council Federation Fellow in the Research School of Information Sciences and Engineering at The Australian National University. He has held academic and substantial visiting positions at the universities of Melbourne, California (Berkeley), Newcastle (Australia), Lund (Sweden), Sydney and Hong Kong (City University).

Room 114 (CDS Library)&lt;br&gt;<br /> <br /> What if sensitive organs prevents a physician from accessing a percutaneous target using a straight, rigid needle? One promising solution involves steering flexible bevel-tip needles. These needles introduce exciting robotics and control systems challenges because the needle tip evolves on a Lie group, and the system exhibits a high degree of nonholonomy.<br /> <br /> In this work, we present image-guided controllers for steerable needles to improve the accuracy of needle insertions. We build upon a previously proposed needle steering model to develop nonlinear observer-based controllers to drive the needle tip to a desired subspace. These controllers are designed to work in conjunction with subspace planners for the needle tip to reach a desired location in human tissue. We show that the tasks of these controllers induces symmetry, thus resulting in a reduced system which greatly simplifies controller and observer design. We propose a method to perform such reductions for generic nonholonomic kinematic systems on Lie groups with left-invariant vector fields. This technique is used to develop controllers for curve-following of a unicycle and subspace-following in needle steering. We show that this &quot;task-induced&quot; reduction lifts to mechanical systems.</div>

<p>Franco: </p> <hr /> <div>My notes for this problem are [[ Media:EF11302007Recitation.pdf | here]]. <br /> The Pade approximation to use should be verified to present the same phase as the delay term &lt;math&gt;e^{-\tau s}&lt;/math&gt;; an approximation of order 2 or 3 will be sufficient. Increasing the order of the approximation will add too many poles and zeros to the transfer function of the process. <br /> <br /> --[[User:Franco|Elisa]]<br /> [[Category: CDS 101/110 FAQ - Homework 8]]<br /> [[Category: CDS 101/110 FAQ - Homework 8, Fall 2007]]</div>

Basic principles of<br /> feedback and its use as a tool for altering the dynamics of systems and<br /> managing uncertainty. Key themes throughout the course will include<br /> input/output response, modeling and model reduction, linear versus nonlinear<br /> models, and local versus global behavior. <br /> <br /> CDS 101 is a 6 unit (2-0-4) class intended for advanced students in science<br /> and engineering who are interested in the principles and tools of feedback<br /> control, but not the analytical techniques for design and synthesis of control<br /> systems. CDS 110 is a 9 unit class (3-0-6) that provides a traditional first<br /> course in control for engineers and applied scientists. It assumes a stronger<br /> mathematical background, including working knowledge of linear algebra and<br /> ODEs. Familiarity with complex variables (Laplace transforms, residue theory)<br /> is helpful but not required. <br /> <br /> === Grading ===<br /> The final grade will be based on homework sets, a midterm exam, and a final exam: <br /> <br /> *''Homework (50%):'' Homework sets will be handed out weekly and due on Mondays by 5 pm to the box outside of 109 Steele. A two day grace period is allowed to turn in your homework. Late homework beyond the grace period will not be accepted without a note from the health center or the Dean. MATLAB code and SIMULINK diagrams are considered part of your solution and should be printed and turned in with the problem set (whether the problem asks for it or not).<br /> <br /> * ''Midterm exam (20%):'' A midterm exam will be handed out at the beginning of midterms period (31 Oct) and due at the end of the midterm examination period (6 Nov). The midterm exam will be open book and computers will be allowed (though not required). <br /> <br /> * ''Final exam (30%):'' The final exam will be handed out on the last day of class (7 Dec) and due at the end of finals week. It will be an open book exam and computers will be allowed (though not required).<br /> <br /> === Collaboration Policy ===<br /> <br /> Collaboration on homework assignments is encouraged. You may consult<br /> outside reference materials, other students, the TA, or the<br /> instructor, but you cannot consult homework solutions from<br /> prior years and you must cite any use of material from outside<br /> references. All solutions that are handed in should be written up<br /> individually and should reflect your own understanding of the subject<br /> matter at the time of writing. MATLAB scripts and plots are<br /> considered part of your writeup and should be done individually (you<br /> can share ideas, but not code).<br /> <br /> No collaboration is allowed on the midterm or final exams.<br /> <br /> === Course Text and References ===<br /> <br /> The primary course text is [[AM:Main Page|''Feedback Systems: An Introduction for Scientists and Engineers'']] by {{Astrom}} and Murray (2008). This book is available in the Caltech bookstore and via download from the [[AM:Main Page|companion web site]]. The following additional references may also be useful:<br /> <br /> * A. D. Lewis, ''A Mathematical Approach to Classical Control'', 2003.

Basic principles of<br /> feedback and its use as a tool for altering the dynamics of systems and<br /> managing uncertainty. Key themes throughout the course will include<br /> input/output response, modeling and model reduction, linear versus nonlinear<br /> models, and local versus global behavior. <br /> <br /> CDS 101 is a 6 unit (2-0-4) class intended for advanced students in science<br /> and engineering who are interested in the principles and tools of feedback<br /> control, but not the analytical techniques for design and synthesis of control<br /> systems. CDS 110 is a 9 unit class (3-0-6) that provides a traditional first<br /> course in control for engineers and applied scientists. It assumes a stronger<br /> mathematical background, including working knowledge of linear algebra and<br /> ODEs. Familiarity with complex variables (Laplace transforms, residue theory)<br /> is helpful but not required. <br /> <br /> === Grading ===<br /> The final grade will be based on homework sets, a midterm exam, and a final exam: <br /> <br /> *''Homework (50%):'' Homework sets will be handed out weekly and due on Mondays by 5 pm to the box outside of 109 Steele. A two day grace period is allowed to turn in your homework. Late homework beyond the grace period will not be accepted without a note from the health center or the Dean. MATLAB code and SIMULINK diagrams are considered part of your solution and should be printed and turned in with the problem set (whether the problem asks for it or not).<br /> <br /> * ''Midterm exam (20%):'' A midterm exam will be handed out at the beginning of midterms period (31 Oct) and due at the end of the midterm examination period (6 Nov). The midterm exam will be open book and computers will be allowed (though not required). <br /> <br /> * ''Final exam (30%):'' The final exam will be handed out on the last day of class (7 Dec) and due at the end of finals week. It will be an open book exam and computers will be allowed (though not required).<br /> <br /> === Collaboration Policy ===<br /> <br /> Collaboration on homework assignments is encouraged. You may consult<br /> outside reference materials, other students, the TA, or the<br /> instructor, but you cannot consult homework solutions from<br /> prior years and you must cite any use of material from outside<br /> references. All solutions that are handed in should be written up<br /> individually and should reflect your own understanding of the subject<br /> matter at the time of writing. MATLAB scripts and plots are<br /> considered part of your writeup and should be done individually (you<br /> can share ideas, but not code).<br /> <br /> No collaboration is allowed on the midterm or final exams.<br /> <br /> === Course Text and References ===<br /> <br /> The primary course text is [[AM:Main Page|''Feedback Systems: An Introduction for Scientists and Engineers'']] by {{Astrom}} and Murray (2008). This book is available in the Caltech bookstore and via download from the [[AM:Main Page|companion web site]]. The following additional references may also be useful:<br /> <br /> * A. D. Lewis, ''A Mathematical Approach to Classical Control'', 2003.

<p>Franco: /* Section 4: Theory */</p> <hr /> <div>{{cds101-fa07}}{{righttoc}}<br /> The purpose of the recitation sections is to provide additional insight into the material for the week, including answer questions on specific topics of interests to the students in that section. The TAs leading the recitation will generally work through one problem from the homework set (same problem in each section) so that students can see what is expected on the homeworks and how the tools from the course can be applied. (Note: students must still work through and turn in the problem that the TAs work through and what you turn in must reflect your understanding of the problem.)<br /> <br /> Recitations for CDS 101/110a will be on Fridays from 2-3 pm unless otherwise noted. Each recitation session is tuned for a slightly different audience and we have made initial assignments based on the course you are taking, the option you are in, and your class standing (So, Jr, Sr, G1, G2, etc). <br /> <br /> === Section 1: Feedback and Control in Nature ===<br /> <br /> This section is designed for students interested in the application of ideas from feedback and control to systems in nature.

<p>Franco: </p> <hr /> <div>The lead controller helps us in two ways: it can increase the gain of the open loop transfer function, and also the phase margin in a certain frequency range. But why could we not use just a PD controller, that increases the phase over a wider range of frequencies?<br /> <br /> The use of the derivative action should always be limited: it helps improve the control performance when the error signal changes rapidly, but for the same reason it could amplify unwanted disturbances on the measured output.<br /> <br /> --[[User:Franco|Elisa]]<br /> <br /> [[Category: CDS 101/110 FAQ - Lecture 9-1]]<br /> [[Category: CDS 101/110 FAQ - Lecture 9-1, Fall 2007]]</div>

<p>Franco: </p> <hr /> <div>This problem focuses on frequency domain specifications and loop shaping. You should learn in fact how to shape the frequency response of a plant so that it will present some desired properties.<br /> <br /> Following the paradigm showed in class (Lecture 8-1, slide 5), you should plot the Bode diagram for the plant considered and mark on such graph the performance specifications required.<br /> <br /> Based on the specifications, you should find what type of controller you need: make sure you understand what yields to gain and phase changes for the overall system. You should not do this by trial and error, but reason in terms of what you need to &quot;add&quot; to the open loop system to have the required behavior; add only the controller terms that are necessary. Don't forget to verify that the new system L(s)=P(s)C(s) satisfies the specifications.<br /> <br /> Finally, you need to plot step and frequency response for the closed loop system, using the known MATLAB commands, finding rise time, overshoot, settling time and steady state error.<br /> <br /> ---[[User:Franco|Elisa]]<br /> [[Category: CDS 101/110 FAQ - Lecture 8-3]]<br /> [[Category: CDS 101/110 FAQ - Homework 7, Fall 2007]]</div>

Basic principles of<br /> feedback and its use as a tool for altering the dynamics of systems and<br /> managing uncertainty. Key themes throughout the course will include<br /> input/output response, modeling and model reduction, linear versus nonlinear<br /> models, and local versus global behavior. <br /> <br /> CDS 101 is a 6 unit (2-0-4) class intended for advanced students in science<br /> and engineering who are interested in the principles and tools of feedback<br /> control, but not the analytical techniques for design and synthesis of control<br /> systems. CDS 110 is a 9 unit class (3-0-6) that provides a traditional first<br /> course in control for engineers and applied scientists. It assumes a stronger<br /> mathematical background, including working knowledge of linear algebra and<br /> ODEs. Familiarity with complex variables (Laplace transforms, residue theory)<br /> is helpful but not required. <br /> <br /> === Grading ===<br /> The final grade will be based on homework sets, a midterm exam, and a final exam: <br /> <br /> *''Homework (50%):'' Homework sets will be handed out weekly and due on Mondays by 5 pm to the box outside of 109 Steele. A two day grace period is allowed to turn in your homework. Late homework beyond the grace period will not be accepted without a note from the health center or the Dean. MATLAB code and SIMULINK diagrams are considered part of your solution and should be printed and turned in with the problem set (whether the problem asks for it or not).<br /> <br /> * ''Midterm exam (20%):'' A midterm exam will be handed out at the beginning of midterms period (31 Oct) and due at the end of the midterm examination period (6 Nov). The midterm exam will be open book and computers will be allowed (though not required). <br /> <br /> * ''Final exam (30%):'' The final exam will be handed out on the last day of class (7 Dec) and due at the end of finals week. It will be an open book exam and computers will be allowed (though not required).<br /> <br /> === Collaboration Policy ===<br /> <br /> Collaboration on homework assignments is encouraged. You may consult<br /> outside reference materials, other students, the TA, or the<br /> instructor, but you cannot consult homework solutions from<br /> prior years and you must cite any use of material from outside<br /> references. All solutions that are handed in should be written up<br /> individually and should reflect your own understanding of the subject<br /> matter at the time of writing. MATLAB scripts and plots are<br /> considered part of your writeup and should be done individually (you<br /> can share ideas, but not code).<br /> <br /> No collaboration is allowed on the midterm or final exams.<br /> <br /> === Course Text and References ===<br /> <br /> The primary course text is [[AM:Main Page|''Feedback Systems: An Introduction for Scientists and Engineers'']] by {{Astrom}} and Murray (2008). This book is available in the Caltech bookstore and via download from the [[AM:Main Page|companion web site]]. The following additional references may also be useful:<br /> <br /> * A. D.

Basic principles of<br /> feedback and its use as a tool for altering the dynamics of systems and<br /> managing uncertainty. Key themes throughout the course will include<br /> input/output response, modeling and model reduction, linear versus nonlinear<br /> models, and local versus global behavior. <br /> <br /> CDS 101 is a 6 unit (2-0-4) class intended for advanced students in science<br /> and engineering who are interested in the principles and tools of feedback<br /> control, but not the analytical techniques for design and synthesis of control<br /> systems. CDS 110 is a 9 unit class (3-0-6) that provides a traditional first<br /> course in control for engineers and applied scientists. It assumes a stronger<br /> mathematical background, including working knowledge of linear algebra and<br /> ODEs. Familiarity with complex variables (Laplace transforms, residue theory)<br /> is helpful but not required. <br /> <br /> === Grading ===<br /> The final grade will be based on homework sets, a midterm exam, and a final exam: <br /> <br /> *''Homework (50%):'' Homework sets will be handed out weekly and due on Mondays by 5 pm to the box outside of 109 Steele. A two day grace period is allowed to turn in your homework. Late homework beyond the grace period will not be accepted without a note from the health center or the Dean. MATLAB code and SIMULINK diagrams are considered part of your solution and should be printed and turned in with the problem set (whether the problem asks for it or not).<br /> <br /> * ''Midterm exam (20%):'' A midterm exam will be handed out at the beginning of midterms period (31 Oct) and due at the end of the midterm examination period (6 Nov). The midterm exam will be open book and computers will be allowed (though not required). <br /> <br /> * ''Final exam (30%):'' The final exam will be handed out on the last day of class (7 Dec) and due at the end of finals week. It will be an open book exam and computers will be allowed (though not required).<br /> <br /> === Collaboration Policy ===<br /> <br /> Collaboration on homework assignments is encouraged. You may consult<br /> outside reference materials, other students, the TA, or the<br /> instructor, but you cannot consult homework solutions from<br /> prior years and you must cite any use of material from outside<br /> references. All solutions that are handed in should be written up<br /> individually and should reflect your own understanding of the subject<br /> matter at the time of writing. MATLAB scripts and plots are<br /> considered part of your writeup and should be done individually (you<br /> can share ideas, but not code).<br /> <br /> No collaboration is allowed on the midterm or final exams.<br /> <br /> === Course Text and References ===<br /> <br /> The primary course text is [[AM:Main Page|''Feedback Systems: An Introduction for Scientists and Engineers'']] by {{Astrom}} and Murray (2008).

<p>Franco: /* Section 4: Theory */</p> <hr /> <div>{{cds101-fa07}}{{righttoc}}<br /> The purpose of the recitation sections is to provide additional insight into the material for the week, including answer questions on specific topics of interests to the students in that section. The TAs leading the recitation will generally work through one problem from the homework set (same problem in each section) so that students can see what is expected on the homeworks and how the tools from the course can be applied. (Note: students must still work through and turn in the problem that the TAs work through and what you turn in must reflect your understanding of the problem.)<br /> <br /> Recitations for CDS 101/110a will be on Fridays from 2-3 pm unless otherwise noted. Each recitation session is tuned for a slightly different audience and we have made initial assignments based on the course you are taking, the option you are in, and your class standing (So, Jr, Sr, G1, G2, etc). <br /> <br /> === Section 1: Feedback and Control in Nature ===<br /> <br /> This section is designed for students interested in the application of ideas from feedback and control to systems in nature. It is also suitable for students who do not have lots of prior coursework in linear algebra, ordinary differential equations or complex variables. All students in CDS 101 are initially assigned to this section. <br /> <br /> &lt;blockquote&gt;<br /> {| width=100% cellspacing=0 cellpadding = 0<br /> |-<br /> | width=50% |<br /> * '''TA:''' Luis Soto<br /> | <br /> * '''Location:''' 110 STL<br /> |- valign=top<br /> | <br /> * Rebecca Barter<br /> * Arkya Dhar <br /> * Stephan Duewel<br /> | <br /> * Alberto Izarraraz<br /> * Lauren LeBon<br /> * Ophelia Venturelli<br /> |}<br /> &lt;/blockquote&gt;<br /> <br /> === Section 2: Ae/ME ===<br /> <br /> This section is intended for students who are interested in the application of feedback and control to mechanical and electro-mechanical systems such as airplanes, cars, robots, etc. <br /> <br /> &lt;blockquote&gt;<br /> {| width=100% cellspacing=0 cellpadding = 0<br /> |-<br /> | width=50% |<br /> * '''TA:''' Sawyer Fuller<br /> | <br /> * '''Location:''' 214 STL<br /> |- valign=top<br /> | <br /> * Balakrishnam, Karthik<br /> * Bozorg-Grayeli, Elah<br /> * Chan, Derek<br /> * Coralic, Vedran<br /> * Cui, Shifu<br /> * Elzinga, Michael<br /> * Feldman, Matthew S.<br /> * Grossman, Marc<br /> * Gutschick, David<br /> * Haderlein, Peter<br /> * Heltsley, Drew<br /> * Hires, Bryan<br /> |<br /> * Kramer, Nick<br /> * Kwa, Timothy<br /> * Liang, Joe<br /> * Man, Han Bin<br /> * Merfeld, Max<br /> * Miller, Madeline<br /> * Paulos, Jimmy<br /> * Roa, Mario<br /> * Sheng, Jing<br /> * Stroup, Adrianne<br /> * Winiarz, Christine<br /> |}<br /> &lt;/blockquote&gt;<br /> <br /> === Section 3: Ae/ME/EE ===<br /> <br /> This section is intended for students who are interested in the application of feedback and control to mechanical and electro-mechanical systems such as airplanes, cars, robots, etc.<br /> <br /> &lt;blockquote&gt;<br /> {| width=100% cellspacing=0 cellpadding = 0<br /> |-<br /> | width=50% |<br /> * '''TA:''' Julia Braman<br /> | <br /> * '''Location:''' 206 TOM<br /> |- valign=top<br /> | <br /> * Arroyo, Jennifer<br /> * Bowers, Steven<br /> * Burt, Jason<br /> * Chen, Jay<br /> * Fuentes Hierro, Manuel<br /> * Grogan, Robert<br /> * Jiang, Michelle<br /> * Ko, Huaising Cindy<br /> * Leichty, John<br /> * Littlepage, Kelly<br /> * Liu, Annie<br /> |<br /> * Liu, Qing<br /> * Pallett, Elliott<br /> * Pantel, Erica<br /> * Spink, Torrey<br /> * Thai, Daniel<br /> * Ueno, Makoto<br /> * Wagner, Glenn<br /> * Wang, Yingying<br /> * Wierman, Matthew<br /> * Wu, Min-Hao<br /> * Zhang, Sebastian<br /> |}<br /> &lt;/blockquote&gt;<br /> <br /> === Section 4: Theory ===<br /> <br /> This section is intended for more advanced students who would like a more theoretical description of some of the tools of the class. This section will not go through a problem from the homework in much detail, but will instead discuss more advanced approaches to the topics being considered for that week. <br /> <br /> * [[EF11092007Recitation.pdf | Notes]] for the recitation of Friday, November 9.<br /> <br /> &lt;blockquote&gt;<br /> {| width=100% cellspacing=0 cellpadding = 0<br /> |-<br /> | width=50% |<br /> * '''TA:''' Elisa Franco<br /> | <br /> * '''Location:''' 102 Steele<br /> |- valign=top<br /> | <br /> <br /> * Best, Melissa<br /> * Bourel, Alexis<br /> * Carson, Vanessa<br /> * Cayco Gajic, Natasha<br /> * Cho, Angela<br /> * Chen, Kevin<br /> * Cruz, Gerardo<br /> | <br /> * Fette, Nicholas<br /> * Li, Na<br /> * Nair, Jayakrishnan<br /> * Nguyen, Nam<br /> * Richards, Andy<br /> * Sharan, Rangoli<br /> * Zhon, Cheng Shan<br /> |}<br /> &lt;/blockquote&gt;<br /> <br /> === Section 5: Off Schedule ===<br /> <br /> This section will be held at on Fridays at 8PM in 214 Steele.

<p>Franco: </p> <hr /> <div>To solve this problem, it is important to have read and understood Chapter 8.2 of AM, in particular the section that talks about transmission of exponential signals. <br /> <br /> <br /> It will be trivial to find the transfer function from u to x (note there is a typo here, y should be x) using the convolution integral.<br /> <br /> For the second part, I suggest to repeat the calculation of the convolution integral, assuming now s=a.<br /> <br /> <br /> <br /> <br /> --[[User:Franco|Elisa]]<br /> [[Category: CDS 101/110 FAQ - Homework 5]]<br /> [[Category: CDS 101/110 FAQ - Homework 5, Fall 2007]]</div>

<p>Franco: </p> <hr /> <div>The point of this exercise is that of practicing your Bode plot sketching skills.<br /> <br /> Part a) Look for simplifications in the transfer function; the information given on the relative magnitude of the parameters of the circuit will allow you to place poles and zeros in the diagram.<br /> <br /> Part b) Here you just have to make a substitution! Note that with the information given, you can find all the numerical coefficients of the transfer function.<br /> <br /> Part c) Not much harder than Part a).<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> --[[User:Franco|Elisa]]<br /> <br /> [[Category: CDS 101/110 FAQ - Homework 5]]<br /> [[Category: CDS 101/110 FAQ - Homework 5, Fall 2007]]</div>

<p>Franco: </p> <hr /> <div>The axes of the Bode plot are log log axes. The x axis is going to have as units the log on base 10 of the frequency considered: if we span &lt;math&gt;\omega&lt;/math&gt; between 0.1 and 10^4, there will be equidistant ticks on the axis corresponding go the log being -1, 0, 1, 2, 3, 4. The way such ticks are labeled is up to you: you can leave the log or write what that corresponds to in &lt;math&gt;\omega&lt;/math&gt;, i.e. .1, 1, 10, 100, 1000, 10000. Same reasoning for the y axis, where you will take the log of the modulus of the transfer function you're considering. The important aspect for sketched Bode plots, is that the ticks on your axes should result in lines of correct slope (0, 1, -1, 2, -2) depending on how many poles/zeros were encountered. <br /> <br /> Many books use units of dB for the y axis instead of just the log scale. Please see this [http://www.cds.caltech.edu/~murray/wiki/Why_is_dB_defined_as_20log_10%3F FAQ] for more information. <br /> <br /> --[[User:Franco|Elisa]]<br /> <br /> [[Category: CDS 101/110 FAQ - Lecture 6-1]]<br /> [[Category: CDS 101/110 FAQ - Lecture 6-1, Fall 2007]]</div>

<p>Franco: /* Section 4: Theory */</p> <hr /> <div>{{cds101-fa07}}{{righttoc}}<br /> The purpose of the recitation sections is to provide additional insight into the material for the week, including answer questions on specific topics of interests to the students in that section. The TAs leading the recitation will generally work through one problem from the homework set (same problem in each section) so that students can see what is expected on the homeworks and how the tools from the course can be applied. (Note: students must still work through and turn in the problem that the TAs work through and what you turn in must reflect your understanding of the problem.)<br /> <br /> Recitations for CDS 101/110a will be on Fridays from 2-3 pm unless otherwise noted. Each recitation session is tuned for a slightly different audience and we have made initial assignments based on the course you are taking, the option you are in, and your class standing (So, Jr, Sr, G1, G2, etc). <br /> <br /> === Section 1: Feedback and Control in Nature ===<br /> <br /> This section is designed for students interested in the application of ideas from feedback and control to systems in nature. It is also suitable for students who do not have lots of prior coursework in linear algebra, ordinary differential equations or complex variables.

<p>Franco: </p> <hr /> <div><br /> V(x) is a Lyapunov function. There is no unique rule to find Lyapunov functions (if they exist) for a given system - see Lecture 3-2. For most mechanical or electrical systems it is possible to find Lyapunov functions by writing down a function that stores the total energy of the system, and analyze its derivative along the system trajectories. Energy dissipation usually indicates that the system has an equilibrium point, where the Lyapunov - energy function reaches zero.<br /> <br /> <br /> ---[[User:Franco|Elisa]]<br /> [[Category: CDS 101/110 FAQ - Lecture 3-1]]<br /> [[Category: CDS 101/110 FAQ - Lecture 3-1, Fall 2007]]</div>
