## Overview

**Monday:** Introduction to Feedback (Slides, MP3)

The goal of this lecture is to introduce some of the basic ideas in feedback systems and provide examples that will allow students to identify and recognize control systems in their everyday world. Two major principles of control--robustness through feedback and design of dynamics--are emphasized throughout the lecture. CDS 101/110 course administration is also covered.

**Wednesday:** Introduction to Control (Slides, MP3)

Control has many applications in engineering systems. This lecture gives an overview of some of those applications and talks about future research directions in control, dynamics and systems. Additional course details about CDS 110 and the course project are also given.

**Friday:** MATLAB Tutorial (Elisa Franco)

This lecture providse an introduction to MATLAB, a software program that will be used extensively throughout the course and on the homework assignments. CDS 110 students who have not used MATLAB in previous courses are strongly encouraged to attend.

## Reading

- K. J. Åström and R. M. Murray, Feedback Systems: An Introduction for Scientists and Engineers, Preprint, 2006. Chapter 1 - Introduction.

## Homework

This homework set is designed to provide some examples and intuition about feedback and control systems. The first problem problem is a conceptual problem designed to provide examples of feedback and control systems in the everyday world. The second problem involves using MATLAB to explore the performance of a engineering feedback system by manually tuning gains and evaluating the resulting performance. The advanced problems (CDS 110 only) further explore these concepts through articles in the popular press about control systems and additional MATLAB/SIMULINK examples.

- Government to Require More Car Safety, Associated Press, September 2006 (problem #4)
