# ECE 382/Spring 2010/Test 3

This page is the review sheet for Test III for ECE 382 in Spring 2010; post any questions or requests for clarification to the discussion portion of this page (see tab above).

## Contents

## Previous Tests

Previous ECE 382 tests are available at Dr. G's Big Box of Random.

## IMPORTANT NOTE!

Test III this year is part closed-book and part open-book.

## Equation Sheet

There will be no equation sheet for the closed-book portion of the test. The open-book portion...is open-book. You will do the closed-book portion first and, upon turning that in, receive the open-book part.

## Test III Spring 2010 Coverage

### Closed Book

Most likely two of these problems; given either an overall transfer function T or a plant G with unity feedback and gain control,

- Range of stability
- Determine appropriate system type, static error constant, and steady-state error
- Root locus sketch including real axis portions, center of asymptote, asymptotes, imaginary axis crossing and gain, estimates of break-in/out

### Open Book / Computer

Main reference for this part is HW 9. Given an overall transfer function T or a "typical configuration" closed loop control system, possibly including an input transducer, output transducer, controller, and plant,

- Range of stability potentially using Maple with Routh
- Root locus using SISOtool
- Design for one criterion using gain control (Ts, Tp, %OS, ess) (i.e. Chapter 8)
- Design PI or lag control to correct steady state error
- Design PD or lead control to correct transient behavior
- Design PID or lag-lead (+ op-amp) to...do both

## Specifically Not On The Test

- Mason's Rule / System Simplification
