This page is the review sheet for Test II for ECE 382 and ME 125 in Spring 2011; 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 part closed-book and part open-book.
Equation Sheet
There will be no equation sheet for the closed-book portion of the test. The open-book portion...is open-book. You will do the closed-book portion first and, upon turning that in, receive the open-book part.
Test II Spring 2010 Coverage
Closed Book
Two or three of these problems; given a block diagram, an overall transfer function T, or a plant G with unity feedback and gain control,
- Determine the system's range of stability (i.e. Routh Array)
- Determine appropriate system type, static error constant, and steady-state error
- Root locus sketch including real axis portions, center of asymptote, asymptotes, imaginary axis crossing and gain, loose (graphical) estimates of break-in/out
Open Book / Computer
Main reference for this part is Chapters 8 and 9. Given an overall transfer function T or a "typical configuration" closed loop control system, possibly including an input transducer, output transducer, controller, and plant,
- Range of stability potentially using Maple with Routh or using SISOtool
- Root locus using SISOtool
- Design for one criterion using gain control (Ts, Tp, %OS, ess) (i.e. Chapter 8)
- Design PI or lag control to correct steady state error
- Design PD or lead control to correct transient behavior
- Design PID or lag-lead (+ op-amp) to...do both
- Design a viable circuit for the above controllers
Specifically Not On The Test
- Nothing excluded as yet
