# ELEC6243 Control System Design (MSc)

## Module Overview

This module is taught together with ELEC3205 Control System Design. ELEC6243 has higher requirements on the desired learning outcomes, which will be assessed by a different set of coursework.

### Aims and Objectives

#### Module Aims

The module aims at providing a set of techniques (including the use of Matlab) for the design of linear multivariable control systems, and to introduce basic nonlinear system analysis and design methods.

#### Learning Outcomes

##### Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• Demonstrate awareness of the current key research issues in control systems design
##### Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

• Design controller using frequency domain methods
• Analyse linear dynamical systems by state space methods
• Derive state space representation from a given transfer function representation
• Check controllability/observability by rank test of the controllability/observability matrix
• Design pole placement state-feedback controller in the state space setting, also with observers in the loop
• Model, analyse, and synthesise nonlinear dynamical systems
• Derive state space representations for nonlinear systems from first principles
• Analyse stability of nonlinear autonomous systems by state space methods
• Analyse nonlinear input--output systems by describing functions
