ECE 4405 Control Systems (3C)
Introduction to the design of feedback compensation to improve the transient and steady-state performance of systems. Course covers modeling techniques, root locus analysis and design, Nyquist criterion, and frequency domain compensation.
What is the reason for this course?
These courses form the basis of control system design. They build on the general system background introduced in ECE 3704 and develop in detail the area of system analysis concerned with control systems.
Typically offered: Fall. Program Area: Systems/Controls.
Prerequisites: C- or better in 3704.
Why are these prerequisites or corequisites required?
The following material from 3704 is required for 4405.
Department Syllabus Information:
Major Measurable Learning Objectives:- model controlled systems in continuous time;
- analyze control systems using root locus and frequency domain techniques;
- design compensators for improved transient and steady-state performance of the closed-loop system.
