Advanced Digital Control

Course title

6M018400

Course content

The course deals with digital control systems, and learn about system modeling (including the transfer from continuous-time to discrete-time), state computation, stability analysis and stabilization, optimal state feedback and observer design. Learn the basic analysis and design of digital control systems, especially when focusing state feedback controller design.

Some discussion may be extended to the case of uncertain systems and LMI based design method. Furthermore, the corresponding simulation and design technique with MATLAB/Simulink software may be introduced.

Purpose of class

The course aims to deliver lectures on the fundamental theory and design method in digital control, which is very important in modern computer-based control. It includes the transformation from continuous-time control systems to discrete-time ones, performance analysis and controller design for discrete-time control systems.

Goals and objectives

Can perform simple modeling analysis and state computation (with or without control input) for digital control systems
Can analyze stability, controllability and observability of digital control systems
Can design state feedback (pole assignment and LQR) and observer for digital control systems
