Controls/Summer 2020/Test 2

Post questions or requests for clarification to the discussion page.

Previous Tests

Previous ECE 382 and ME 344 tests are available at Dr. G's Big Box of Random.

IMPORTANT NOTE!

Test 2 this year is open-book and will not have a computational component to it.

Equation Sheet

When this test was closed book, students were allowed to crowd source an equation sheet. Here's the one they came up with in Fall 2016: Test 2 Equation Sheet Fall 2016 (pdf).

Test 2 Spring 2020 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. It will be similar to, though not the same as, Test 2 from Fall 2016. Also:

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.

Similar to Test 2's from 2011-2012

• Determine steady state error for step, ramp, parabolic inputs.
• Determine steady state error due to disturbances.
