This page is the review sheet for Test II for [[ECE 382]] in [[ECE 382/Spring 2009|Spring 2009]]; post any questions or requests for clarification to the discussion portion of this page (see tab above).

==Coverage ==
The sections listed by chapter below may be in the closed or open part of the test; the computational tools will only be in the open part.
===Chapter III===
* Set up state space equations for electrical, mechanical, and hybrid systems.
* Set up phase space equations from a differential equation or transfer function.
===Chapter IV===
* 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.

===Chapter V===
* Translate a block diagram into a signal flow graph.
* Determine the transfer function of a signal flow graph.
===Chapter VI===
* 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.
===Chapter VII===
* Find system type, static error constants, and steady state error for unity feedback systems.
* Determine equivalent forward transfer function for systems not fitting the unity feedback paradigm, and find system type, static error constants, and steady state error for those systems.
* Design a system satisfying both stability and error considerations.
<!-- not in Spring 2009
===Computational Tools===
* MATLAB: Determine step response characteristics for a system using the <code>step</code> command.
* MATLAB: Use <code>tf</code> and <code>zpk</code> functions to set up transfer functions.
* MATLAB: Use <code>parallel</code> and <code>feedback</code> functions along with algebra to generate transfer functions of cascade, parallel, feedback, and more complex systems.
* MATLAB: convert between polynomial ratio and zero-pole-gain representations of transfer functions.
* MATLAB: Model a system using Simulink and make a plot of the input and output of the system.
* MATLAB: Model a system using the <code>lsim</code> command and determine steady-state error graphically.
* MAPLE: Solve and simplify transfer functions.

<!-- not in Spring 2009 due to OIT malfunction
* MAPLE: Generate and translate a Routh array.

==Community Equations==
For the closed part of the test, I will provide an equation sheet.  Trick is, you have to generate it.  Put your requests for equations you want on the discussion portion of this page no later than 11:59PM on Tuesday, March 24th.  I will approve or deny that evening and post the final set by Wednesday, March 25th.  I will make the copies of the equations a part of the test; you do not need to bring your own sheet.
