EE 432 - Control System Theory

    • EE 432 Lecture Workbook (approx. 700 pages), G. Dempsey, January 2007.
    • Primary Reference: Feedback Control Systems, 4th edition, Prentice-Hall, Phillips & Harbor.
    • References:

1. Feedback Control of Dynamic Systems, 2nd edition, Franklin, Powell, Emami- Naeini.

2. Automatic Control Systems, 7th edition, Benjamin Kuo.

    • Prerequisite: EE 431
    • Course Description:

The course consists of modeling electrical, mechanical, hydraulic and thermal systems, analysis of linear systems in the time and frequency domains, stability concepts and compensation design in the time and frequency domains. Classical control will be emphasized. The software programs MATLAB, the Controls System Toolbox, and SIMULINK will be incorporated into the lectures, homework, and tests.

    • Course and Grading Policy:

Homework will be assigned each class period and collected the next class period. Homework assignments will not count as part of the course grade. Your grade in EE 432 is determined from your performance on four tests (25% each). There is no final exam. Borderline grades are determined by three design projects, percentage of homework completed, class participation and attendance. Regular attendance is expected. Prior consent must be given before postponement of an exam. An unexcused absence for an examination will receive a grade of zero. Makeup exams are not given. If a student is excused from one of the tests, they are required to complete a final comprehensive exam. More than one missed test requires dropping the course.
