Control Systems

Fall 2008

 

Description:      EEC 440 Control Systems (4-0-4). Prerequisites: EEC 314. Analysis and design of feedback control systems. Topics covered include: the use of feedback; modeling and the use of mathematical model in understanding behavior of dynamic systems; useful design tools such as PID, root-locus, loop shaping, pole placement; robustness in stability and performance; real world problem solving using control theory; digital control characteristics and design methods.

 

Goal:                This course is designed to give students the ability to: understand the basic concepts of feedback and see how they are used for control purposes; derive mathematical model based on first principle or time response and relate its parameters to the behavior of dynamic systems; solve control problems by using appropriate design tools; understand design constraints such as model inaccuracies and actuator saturation, and produce robust control solutions; implement the controller digitally.

Resources:        Matlab, Simulink and the Control System Toolbox are used extensively. They are available in the engineering computer lab, but purchase is recommended.

 

Project:            A serial project will be assigned to let you practice what you learn.  You are encouraged to perform research independent of the class material, but all external material must be referenced and assistance acknowledged.  This is not a team project; all reports must be in your own words, and plagiarized reports will be given a grade of zero.  Late reports will be accepted, with an automatic reduction in the score.  Reports must be neat, precise, correct, and logically presented using the distributed reference (V. Li, Hints on writing technical papers and making presentations, IEEE Transactions on Education, vol. 42, pp.134-137, May 1999).  The report should be stapled in the upper left corner.  You will be graded on presentation as well as content.  Proofread your work for spelling and grammar errors. 

 

Tests:               Exams will be closed-book with one 8½ x 11 note sheet.  Blank worksheets will be provided.  No electronic devices (e.g., calculators or laptops) will be necessary or allowed.  No makeup quizzes or exams will be given; you can be excused, however, from a test/quiz in case of an emergency if a written note is provided.
