ECE 516: System Control Engineering

This course focuses on the analysis and design of systems control. This course will introduce time-domain systems dynamic control fundamentals and their design issues for electrical engineering applications. Emphasis will be on linear, time-invariant, multi-input multi-output continuous time systems. Topics include open and closed-loop state-space representations, analytical solutions, computer simulations, stability, controllability, observability, pole-placement controller/observer design, and introduction to optimal control. ECE 301 (Linear Systems) or equivalent is the pre-requisite for this course. A strong background in linear algebra and differential equations is not required but is highly recommended. The MATLAB/SIMULINK computer software package will be used extensively to assist in the understanding of concepts and fundamentals of system dynamics and control, and also to analyze and design control systems.

Grading Scheme

Exams and homework will be based mainly on the basic material. Recommended materials will be presented once a while for your entertainment, and optional materials will be presented once a long while for your imaginations.

A.  Homework (approximately 6 – 9 assignments):                         30%

B.  Mid-term Exam:                                                                          30%

C.  Final Exam:                                                                                 40%

The problems of exams will be based mainly on lecture materials and the textbook.


Your Class Grade = MAX {Relative standing, Absolute standing}, where

(a) Relative standing

The whole class grade will be “curved” and your grade will be based on your relative standing in the class.

(b) Absolute standing (AS – average score)

A+: AS ³ 98% A: 98%> AS ³ 92% A-: 92%> AS ³ 90%
B+: 90% > AS ³ 88% B: 88% > AS ³ 82% B-: 82% > AS ³ 80%
C+: 80% > AS ³ 78% C: 78% > AS ³ 72% C-: 72% > AS ³ 70%
D+: 70% > AS ³ 68% D: 68% > AS ³ 62% D: 62% > AS ³ 60%
F: 60% > AS
