### ECE 6744 Linear Control Theory (3C)

Advanced introduction to the theory of optimal control of time-varying and time-invariant linear systems; Solutions to the linear-quadratic regulator, optimal filtering, and linear-quadratic-gaussian problems; Robustness analysis and techniques to enhance robustness of controllers.

What is the reason for this course?

This course provides a rigorous introduction to linear optimal control systems. The emphasis is on being able to derive the fundamental properties of these systems as well as to provide an introduction to important theoretical tools such as dynamic programming and least-squares optimization in function spaces.

Typically offered: Spring. Program Area: Systems/Controls.

*Prerequisites: Prerequisites: ECE 5744 or ECE 5754 or ME 5544 or ME 5554 or AOE 5744 or AOE 5754*.

*ECE 6744 is a new course, and ECE 5404 is being deleted. Cross-listed with ME (6544) and AOE (6744).*
