'''A Framework for Structural Input/Output and Control Configuration Selection of Large - Scale Systems'''<br />
<br />
The structure control system design consists mainly of two steps: input/output (I/O) selection and control configuration (CC) selection. The first one is devoted to the problem of computing how many actuators/sensors are needed and where should be placed in the plant to obtain some desired property. Control configuration is related to the decentralized control problem and is dedicated to the task of selecting which outputs (sensors) should be available for feedback and to which inputs (actuators) in order to achieve a predefined goal. The choice of inputs and outputs affects the performance, complexity and costs of the control system. Due to the combinatorial nature of the selection problem, an efficient and systematic method is required to complement the designer intuition, experience and physical insight.<br />
<br />
Motivated by the above, this presentation addresses the structure control system design taking explicitly into consideration the possible application to large - scale systems. We provide an efficient framework to solve the following major minimization problems: i) selection of the minimum number of manipulated/measured variables to achieve structural controllability/observability of the system, and ii) selection of the minimum number of measured and manipulated variables, and feedback interconnections between them such that the system has no structural fixed modes. Contrary to what would be expected, we showed that it is possible to obtain the global solution of the aforementioned minimization problems in polynomial complexity in the number of the state variables of the system. To this effect, we propose a methodology that is efficient (polynomial complexity) and unified in the sense that it solves simultaneously the I/O and the CC selection problems. This is done by exploiting the implications of the I/O selection in the solution to the CC problem.<br />

'''A Framework for Structural Input/Output and Control Configuration Selection of Large - Scale Systems'''<br />
<br />
The structure control system design consists mainly of two steps: input/output (I/O) selection and control configuration (CC) selection. The first one is devoted to the problem of computing how many actuators/sensors are needed and where should be placed in the plant to obtain some desired property. Control configuration is related to the decentralized control problem and is dedicated to the task of selecting which outputs (sensors) should be available for feedback and to which inputs (actuators) in order to achieve a predefined goal. The choice of inputs and outputs affects the performance, complexity and costs of the control system. Due to the combinatorial nature of the selection problem, an efficient and systematic method is required to complement the designer intuition, experience and physical insight.<br />
<br />
Motivated by the above, this presentation addresses the structure control system design taking explicitly into consideration the possible application to large - scale systems. We provide an efficient framework to solve the following major minimization problems: i) selection of the minimum number of manipulated/measured variables to achieve structural controllability/observability of the system, and ii) selection of the minimum number of measured and manipulated variables, and feedback interconnections between them such that the system has no structural fixed modes. Contrary to what would be expected, we showed that it is possible to obtain the global solution of the aforementioned minimization problems in polynomial complexity in the number of the state variables of the system. To this effect, we propose a methodology that is efficient (polynomial complexity) and unified in the sense that it solves simultaneously the I/O and the CC selection problems. This is done by exploiting the implications of the I/O selection in the solution to the CC problem.<br />

Title: Linear Quadratic Regulation (LQR) for Time-Varying Systems with Delay<br><br />
Thu, 12 pm -- 213 Annenberg<br />
<br />
In this talk, linear quadratic regulation (LQR) for time-varying systems with delay is used to optimize the control gains for connected cruise control (CCC). We assume that the CCC vehicle receives kinematic information through wireless vehicle-to-vehicle (V2V) communication from several vehicles ahead. An optimized feedback law is obtained by minimizing a cost function defined by distance and velocity errors and the acceleration of the CCC vehicle on an infinite horizon. Communication delays, driver reaction times, and heterogeneity among vehicles are taken into account. We show that the feedback gains can be obtained recursively as signals from vehicles farther ahead become available, and that the optimal gains decay with the number of cars between the source of the signal and the CCC vehicle. To ensure smooth traffic flow the head-to-tail string stability is investigated and the robustness against connectivity loss and delay variations is tested. The analytical results are verified by numerical simulations of connected vehicle systems</div>Yilinmohttps://murray.cds.caltech.edu/index.php?title=File:Handout.pdf&diff=17735File:Handout.pdf2014-11-20T19:44:54Z<p>Yilinmo: handout on intrusion detection for control systems for CDS 270 lecture 16</p>

Optimal Selective Attention and Action in Reactive Agents <br><br />
Roy Fox, Hebrew University<br />
<br />
2 Oct (Thu), 12 pm <br><br />
106 Annenberg<br />
<br />
Intelligent agents, interacting with their environment, operate under constraints on what they can observe and how they can act. Unbounded agents can use standard Reinforcement Learning to optimize their inference and control under purely external constraints. Bounded agents, on the other hand, are subject to internal constraints as well. This only allows them to partially notice their observations, and to partially intend their actions, requiring rational selection of attention and action.<br />
<br />
In this talk we will see how to find the optimal information-constrained policy in reactive (memoryless) agents. We will discuss a number of reasons why internal constraints are often best modeled as bounds on information-theoretic quantities, and why we can focus on reactive agents with hardly any loss of generality. We will link the solution of the constrained problem to that of soft clustering, and present some of its nice properties, such as principled dimensionality reduction.</div>Yilinmohttps://murray.cds.caltech.edu/index.php?title=Tomoaki_Hashimoto,_Aug_2014&diff=17563Tomoaki Hashimoto, Aug 20142014-07-24T22:07:48Z<p>Yilinmo: </p>

Abstract: Model predictive control (MPC), also known as receding horizon control, is a type of optimal feedback control where control performance<br />
over a finite future is optimized with a performance index that has a moving initial time and a terminal time. This talk provides two topics about MPC. <br />
One is a design method of MPC for thermal fluid systems governed by nonlinear partial differential equations [1]. The other one is probabilistic constrained<br />
MPC for linear discrete-time stochastic systems. Both topics are related to the recent development of MPC. In particular, we would like to review the<br />
background and key idea of these studies [1, 2] rather than the technical details.<br />

Computational Issues in Nonlinear Control<br />
<br />

3 March 2014 - 11:00am PST, 121 Annenberg<br />
<br />
Over the past several decades there has been tremendous progress in the development of nonlinear systems theory but implementation of these ideas have lagged behind because of the lack of effective computational tools. Frequently the nonlinear theory requires the solution of partial differential equations in continuous time and functional equations in discrete time. Algorithms for these have been developed but further work is needed to make them broadly and easily accessible. We believe that computational nonlinear control is in a similar stage of development that computational linear control was in around early 1980s. Then there was a well developed theory of linear control but computational tools lagged behind. Soon after comprehensive tools such as MATLAB and Matrix X were developed and put to great use in implementing the linear theory. Advancements in numerical methods together with the exponential increase in computational power has made it possible to solve complex nonlinear problems, many of which are closely related to control systems applications. Developing computational algorithms and software tools for such control systems are not only promising, but also necessary.<br />

How Much Modeling Information Is Really Needed for Feedback Control?<br />
<br />
Dennis Bernstein<br><br />
University of Michigan<br />
</center><br />
<br />
Modeling for control is often expensive and time-consuming—not to mention futile, especially when a plant changes unpredictably. Our research is therefore aimed at the following fundamental question: What is the minimal modeling information (order, parameters, nonlinearities, noise spectra, etc.) that must be known—and how *well* must it be known—so that a controller can reliably meet performance specifications? <br />
The approach we are developing is based on retrospective cost adaptive control (RCAC), which uses retrospective optimization for online learning. RCAC is easy to implement, and requires extremely limited modeling information. In this talk I will explain the rationale for RCAC, its applicability to various types of plants (stable/unstable, minimum-phase/NMP, SISO/MIMO, linear/nonlinear), the modeling information it can operate with and (especially) without, and the status of its theoretical foundation.<br />
For flight control, we will apply RCAC to the extreme case of totally unknown control-surface faults, such as a stuck rudder or severe rate saturation. Additional examples are taken from missile control, noise and vibration control, and spacecraft attitude control with nonlinear actuation such as CMGs.</div>Yilinmohttps://murray.cds.caltech.edu/index.php?title=Dennis_Bernstein,_Jan_2014&diff=16854Dennis Bernstein, Jan 20142014-01-28T00:09:11Z<p>Yilinmo: </p>
