FEEG2004 Electronics, Drives and Control
Practicing Mechanical and Acoustical Engineers require a working knowledge of aspects of electronics, electrical machines and control systems, as these elements are regularly encountered, for example, when instrumenting mechanical/acoustic structures with sensors, providing electro- mechanical actuation and ensuring stable system control and operation. This module provides students with the necessary theory of these elements, wor e domain, and two laboratory exercises to re-enforce the taught material.
Aims and Objectives
- impart an appreciation of the use of electronics in a wider systems sense and an understanding of its relevance in control applications - endow students with the ability to design simple analogue and digital circuits to enable interfacing of transducers with controllers/data acquisition systems, in support of future project work for example - teach transferrable skills such as algorithm design and an appreciation of the hardware/software trade-offs in their implementation - to gain an appreciation of electrical machine types and basic machine drive control - establish the fundamental techniques for modelling dynamic systems. - analyse and manipulate system models in the time and frequency domain. - develop an understanding of feedback control systems and the parameters that influence their stability and performance.
