Previous Tests
Previous ECE 382 and Controls tests are available at Dr. G's Big Box of Random.
IMPORTANT NOTE!
Test 2 this year is closed-book and will not have a computational component to it.
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 Controls/Fall 2015/Test 2/RSR each day until Noon the day 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 2 Spring 2012 Coverage
This test comes primarily from Chapters 1-7, excepting Chapter 3. Material from Homework 1-6 will be covered. The focus will be on Chapters 4-7.
Similar to Test 2's from 2007-2010 and Test 1's from 2011-2012
- 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.
- Translate a block diagram into a signal flow graph.
- Determine the transfer function of a signal flow graph.
- 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.
