The goal of this lecture is to introduce some of the basic ideas in feedback and control 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.

CDS 101/110a Schedule Recitations FAQ ()

Overview

The learning objectives for this week are:

  • Students should know what a feedback system is and how to identify the key components and properties of a control system in the everyday world
  • Students should be able to model a simple system (using ODEs) and use their model to make predictions about the behavior of a system
  • Students should be able to use MATLAB and SIMULINK to run a simulation of a control system and generate plots showing the performance of the system

Monday: Introduction to Feedback and Control (Slides, MP3) The goal of this lecture is to introduce some of the basic ideas in feedback and control 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: Review of Modeling using ODEs (Slides, MP3- last year's lecture)

  • NOTE: Due to technical difficulties, this Wednesday's lecture was not recorded. Sorry for the inconvenience.

This lecture provides an overview of modeling for control systems. We discuss what a model is and what types of questions it can be used to answer. The concepts of state, dynamics, inputs and outputs are described, including running examples to demonstrate the concepts. Several different modeling techniques are summarized, with emphasis on differential equations. Two examples are included to demonstrate the main concepts.

Friday: Matlab Tutorial

This lecture provides an introduction to MATLAB/SIMULINK, a software package that will be used extensively throughout the course and on the homework assignments. Students who have not used MATLAB and SIMULINK in previous courses are strongly encouraged to attend. Note: This tutorial will be offered from 2-4 pm and 4-6 pm in 328 SFL. Students may attend either session.

Reading

The reading for the week is out of the main text. The material in Chapter 2 should be review (Ph1, Ma 2, mainly), but introduces some important concepts in terms of control-oriented modeling (inputs, outputs, state). Section 3.1 gives an overview of the cruise control model, which is part of this week's homework.

  • K. J. Åström and R. M. Murray,, Princeton University Press, 2008
    • - Read sections 1.1-1.2 and 1.4-1.5 (skim 1.3) [30 min]
    • - Read sections 2.1-2.3 [30 min]
    • - Skim section 3.1 (cruise control model) [10 min]

Students interested in more advanced material should read Chapter 1 of Lewis:

In addition, for the MATLAB/SIMULINK tutorial, students may want to have a look at MATLAB basics, part of the Control Tutorials for MATLAB web site.
