Previous Tests

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


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 on Friday before the test, at which time the equation sheet will be set. The actual equation sheet will be available by 11:59PM the Friday before the test; a copy will be handed out with the test as well - you do not need to bring your own and cannot use your own.

Test 2 Fall 2015 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.
