Key words
control, systems, PID
Objectives
Learning the basic techniques to control and approve the behaviour of simple linear dynamic systems
Topics
Concepts:
How to influence processes? Which configurations? What is control? What is feedback? What's the meaning of direct and indirect control-action, cascade, feedforward? The industrial relevance of control theory.
Analysis:
Characteristics and performance of a feedback control loop in time-domain and in frequency-domain. Closed-loop stability, suppression of disturbances, robustness, servosystems, bandwidth, static behaviour and errors, transients, gainmargin, phasemargin. The use of dedicated computertools.
Design:
Design of controlsystems in time-domain and frequencydomain. Traditional PID-controller with algorithms and tuning. Design of dynamic compensators through root-locus techniques and through frequency domain techniques. The use of CACSD-tools.
Prerequisites
final objectives of "wiskunde", "fysica", "netwerkanalyse", "signalen en systemen"
Final Objectives
To be able to make a mathematical analysis of the components used in productionautomation
To be able to analyse controlloops
To be able to design simple controlloops
Materials used
Coursebook: Nise, Control Systems Engineering (Dutch version)

Study costs
Purchase of coursebook + handouts lab: approx. 60 euro
Study guidance
By appointment
Teaching Methods
1) Ex Cathedra
2) Lab sessions to practice the theoretical concepts through computersimulations and simple real life processes.
3) Project (more complex control system design)
Assessment
1) Oral examination (partially closed & open book)
2) Permanent evaluation (labs & projects)
weight: theory/lab = 2/1
A weighted average is used to compute the final score for a training item.
However, if a student gains a score of 7 or less on 20 on one of the different courses
(parts of training items) , he proves that his skill for certain subcompetencies is
insufficient. Consequently, one can turn from the arithmetical calculation of the final
assignment of quotas of a training item and the new marks can be awarded on consensus.
Of course, the examiners can judge that the arithmetic regulations mentioned in the
study index card can also be used for 7 or less.
For each deviation a detailed motivation ought to be drawn up. In that case one should
point out that the skill for this subcompetency is proven to be insufficient,
if the student didn’t pass the partim that is considered to be important
for certain subcompetencies.
