Aims:


This module aims to bring together many aspects of cybernetic systems, to underline many of
the principles of feedback and to show how a computer controlled feedback system may be
implemented.


Intended learning outcomes:


Assessable outcomes

By the end of the module the students should be able to analyse and design computer
controlled feedback systems.


Additional outcomes

EA2 topics: Feedback systems design and analysis; Report writing

Principles of Feed

theoretical developments of Nyquist and Bode, covering phase

loops for high loop gain amplifiers
. Examples both in control (eg. velocity feedback in
servos) and electronics (power amplifier output stages).


Half of the module is the Princ
iples of Feedback course, the other half is Computer Control.
The examination paper comprises one question on one computer controlled feedback system.


Brief description of teaching and learning methods:


The module comprises 2 lectures per week, assignmen
