Key words
Objectives
The course provides a basic inside in the measuring and controlling
processes of automation. Practical insight is gained through case studies of
thermal, pneumatic, hydraulic en electrical systems. The link with the
processcomputertechnology is explained. The student learns the mathematical
techniques for the systemanalysis in the time and frequencydomain.
The behaviour of different controlstrategies are explored. The correct
tuning of controllers is learned through stabilityresearch,
stability-correction and the necessary basic practise rules for tuning.
Topics
1. Fundamentals of Automatic control.
Basic definitions, examples of simple control systems; different
implementations of control, classification of controllers and systems, delay
in control systems.
2. Laplacetransformation
Definitions, properties, transformationrules and the inverse transformation.
3. Transferfunction and blockdiagrams.
Definitions, properties, transformationrules and practical examples.
4. Analysis of the tuningalgorithms.
