SESG6036 Advanced Control Design

Module Overview

This module covers the topics on advanced control systems analysis and design. To attend this module, students are expected to have learned the classical continuous-time control analysis and design, both in the frequency domain and the time domains. Basic understanding and knowledge of nonlinear systems is also required. In this module, the discrete-time counterparts of the continuoustime control analysis and design will be studied, motivated by the common implementation of controllers using microprocessors or computers. How to handling uncertainty in engineering by advanced control techniques, e.g., robust control and adaptive control will also be studied. Both the theoretical aspects and some of the practical aspects of discrete-time are discussed.

Aims and Objectives

Module Aims

• To provide students with an introduction to advanced theory and techniques of control system analysis and design, as well as some issues in their implementation, both in linear and nonlinear framework. • To introduce several application areas of advanced control techniques, especially those related to electro-mechanical systems, active vibration and noise control, and aero systems.
