Previous Tests

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

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.

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.
