Module Overview

Vibrations

The module reinforces the modelling and vibrations knowledge gained by students at undergraduate level. Building on these skills and mathematical tools, vibrations in more realistic and complex structures are investigated and analysed, increasing the understanding of vibration problems in engineering structures.

Acoustics
In the Acoustics part of the module, the aim is to impart knowledge of the sources and nature of acoustic noise in an engineering environment. The coverage starts with basic physical concepts and leads on to the treatment of vibrating structure/fluid interactions for a number of simple examples of practical interest.

Control

The main aims of the digital control systems part of the module are:

  • To give students an appreciation of the need for modern control systems
  • To explain and discuss the systems that make up modern control systems
  • To provide students with mathematical tools needed in the design and performance analysis of digital control systems
