ECE 38200 - Feedback System Analysis and Design

Lecture Hours: 3 Credits: 3

Counts as:
EE Advanced Selective
CMPE Complementary Elective

Normally Offered: Each Fall, Spring

Requisites:
ECE 30100

Catalog Description:
In this course classical concepts of feedback system analysis and associated compensation techniques are presented. In particular, the root locus, Bode diagram and Nyquist plot are used as determinants of stability.

Course Objectives:
After completion of this course the student should be able to construct a block diagram, signal flow graph and mathematical model for a lumped parameter physical system consisting of some common mechanical and electrical components. The student should be able to perform sensitivity and stability analyses of such systems, to design cascade and feedforward compensators for such systems to meet standard specifications on the transient and frequency response and to use the digital computer to check if the specifications are met.

Required Text(s):
