ECE 4406 Control Systems (3C)

Extension of the techniques of 4405 to systems controlled by digital compensators. Course covers discrete-time modeling of continuous-time systems, discrete-time redesign of continuous controllers, root-locus compensation, frequency domain compensation, and advanced toics in digital control.

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: Spring. Program Area: Systems/Controls.

Prerequisites: C- or better in 4405.

For More Information, see the news article, "A Quieter Headset, Nearly Perfect Results."
