# ECE 382/Spring 2010/Test 2

This page is the review sheet for Test II 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 II this year is closed-book and will **not** have a computational component to it. Though you will be taking the test in the lab room, that is primarily so you have extra time to complete the work.

## Equation Sheet

The class will come up with an equation sheet. Post the equation that you would like to the discussion page of this article; I will generate the list of approved and disapproved equations at ECE 382/Spring 2010/Test 2/RSR each day until Noon two days before the test, at which time the equation sheet will be set. The actual equation sheet will be available by 11:59PM the day before the test; a copy will be handed out with the test as well.

## Test II Spring 2010 Coverage

### Chapter III

- Set up state space equations for electrical, mechanical, and hybrid systems.
- Set up phase space equations from a differential equation or transfer function.

### Chapter IV

- Determine characteristics of the step response for a first-order system or design a system to achieve those characteristics. Specifically, rise time and settling time.
- Determine the characteristics of the step response for a second-order system or design a system to achieve those characteristics. Specifically for a second-order underdamped system: rise time, peak time, %OS, settling time, damping, natural frequency, and damped frequency.
- Know when extra poles and zeros interfere with the assumptions of a dominant pair of poles.

### Chapter V

- Translate a block diagram into a signal flow graph.
- Determine the transfer function of a signal flow graph.

### Chapter VI

- Generate a Routh array for a transfer function and determine regions of stability. Be sure to know how to handle rows with all zeros and rows with leading zeros.
- Find the value of one or more free parameters to obtain marginal stability and the frequency of oscillation for marginal stability.

### Chapter VII

- Find system type, static error constants, and steady state error for unity feedback systems.
- Determine equivalent forward transfer function for systems not fitting the unity feedback paradigm, and find system type, static error constants, and steady state error for those systems.
- Design a system satisfying both stability and error considerations.

## Specifically Not On The Test
