Course Description

This course introduces the fundamentals of feedback systems and methods for control system design and analysis. Examples from a variety of applications, such as electrical, mechanical, biological, and information technology systems, will be used to illustrate how the concepts from control theory can be applied in practice. The course presents a wide range of fundamental results in control theory developed in the past 50 years. Topics include state space models, stability, Lyapunov functions, linear systems, state feedback, reachability, stabilization, observability, state estimation, Kalman filtering, transfer functions, frequency domain analysis and design, Bode plot, Nyquist criterion, and PID control.
