About Us ABET ECE 1673Linear Control Systems(4 credits) Description: Introduction to feedback control systems, mathematical models, second order systems response and identification, system types, steady-state errors, root locus analysis and design, Bode plots, Nyquist theory and frequency domain compensation techniques. Includes a laboratory. Prerequisites: ECE/COE 0041, Math 0250 Text: Charles L. Phillips and Royce D. Harbor, Feedback Control Systems, Third Edition, Prentice Hall, Englewood Cliffs, NJ Course Objectives: To understand and practice the analysis and design of linear analog feedback control systems. To use the MATLAB software to perform simulations of the behavior of physical systems. To experiment with controlling physical systems in the laboratory, and to relate the behavior of the physical systems to the mathematical models developed in the lecture. Topics Covered: Transfer function models of linear systems, state-variable models, time response and frequency response, closed-loop control system design specifications, stability analysis, root locus techniques for analysis and design of closed-loop systems, frequency response analysis and design: Bode plots and the Nyquist criterion, design of PID controllers, phase-lead and phase-lag compensators, introduction to modern control design Class/Laboratory Schedule: Class meets twice per week; 75 minutes per session. Students must complete approximately eight homework assignments, some of which require programming in MATLAB. The students also are given approximately eight quizzes. Lab meets once per week; 3 hours per session. The students must complete 5 experiments using the servo system and 3 experiments using the inverted pendulum equipment. Professional Component Contributions: The practical aspects of control system design are stressed: the students practice the same procedures for control system design (including the use of computer simulations) as are commonly practiced by control engineers in industry. The course is a laboratory course and strengthens the student’s technical competencies through experience in applying analytical techniques to physical systems. Students work in teams in the laboratory and prepare written reports on experiments. Applications outside of electrical systems are discussed. MATLAB is used throughout the course. Prepared by:J.R. Boston and Raymond C. Vasko, Jr. Date Prepared: December 2004
