Goals: The purpose of this course is to present the structure of and solution techniques for feedback control theory to provide the student with a knowledge of modern analog and digital control system practices.
Prerequisites by Topic:
1. Electronic Devices and Models
2. Linear Systems Theory
Topics:
1. Computer Project - Basic Feedback principles (2 classes)
2. Review of electrical network fundamentals and Laplace transform methods (3 classes)
3. Transfer functions (4 classes)
4. Block diagram manipulations, signal flow graphs, and Mason's gain rule (5 classes)
5. Root distributions, stability testing (3 classes)
6. The feedback concept; steady-state errors, sensitivity, and the use of performance indices (6 classes)
7. Root locus methods (6 classes)
8. Compensation methods (5 classes)
9. Frequency response methods; incorporating experimental data (2 classes)
10. Tests and solutions (6 classes)
Computer Usage: Two homework assignments require students to write and execute program for analysis of control systems. Typical problems are to compute rise time, overshoot, and settling time for a system which is not a simple quadratic, and a state variable matrix solution. FORTRAN and BASIC are the most commonly used languages along with PSPICE circuit analysis program.
Computer project: Studying effects of positive, negative, and no feedback on a basic control system. Root locus using VisSim.
