## Announcements

 Archive
• 19 Feb 07: due to the institute holiday, the Monday office hour this week will be held on Wednesday from 12-1 in Powell-Booth, room 100.
• 15 Feb 07: the midterm solutions are posted.
• 14 Feb 07: Week 6 - Two Degree of Freedom Control Design (HW #6)
• 12 Feb 07: this week Prof. Murray will hold a recitation section on Friday 16, instead of a course project lecture. Topics will include examples from HW # 6.
• 12 Feb 07: the graded midterm can be picked up in the Steele CDS 110b return bin. The average was 30.3 and the standard deviation was 7.84. To compute your rough grade for the course so far, use the following formula
<amsmath>

\text{score} = \frac{\sum_{i=1}^4 \text{HW}_i}{130} \cdot 25 + \frac{\text{MT}}{50} \cdot 20

</amsmath>
If you divide this by 40 (to account for the curve), you will get your rough percentage score for the course (with A = 90-100%, B = 80-89%, etc).

## Course Syllabus

Course Desciption and Goals: CDS 110b focuses on intermediate topics in control theory, including state estimation using Kalman filters, optimal control methods and modern control design techniques. Upon completion of the course, students will be able to design and analyze control systems of moderate complexity. Students may optionally participate in a course project in lieu of taking the midterm and final. Students participating in the course project will learn how to implement and test control systems on a modern experimental system.

The final grade will be based on homework sets, a midterm exam and a final exam:

• Homework: 50%
Homework sets will be handed out weekly and will generally be due one week later at 5 pm to the box outside of 109 Steele. Late homework will not be accepted without prior permission from the instructor.
• Midterm: 20%
A midterm exam will be handed out at the beginning of midterms week and due at the end of the midterm examination period. The midterm exam will be open book.
• Final: 30%
The final exam will be handed out on the last day of class due at the end of finals week. It will be an open book exam.

### Collaboration Policy

Collaboration on homework assignments is encouraged. You may consult outside reference materials, other students, the TA, or the instructor. All solutions that are handed in should reflect your understanding of the subject matter at the time of writing. MATLAB scripts and plots are considered part of your writeup and should be done individually.

No collaboration is allowed on the midterm of final exams.
