Remarks (specific information about assesment, entry requirements, etc.):
Goals:
The basic concept of control techniques are introduced. Why to control a system, what performance is desired, how can it be achieved. The classical time domain and frequency domain techniques are introduced and made operational
Computer use:
Only as demonstration during the lectures the computer applications are shown with MATLAB/Simulink.
Laboratory project(s):
A computer practicum is used to experience the control techniques.
Design content:
The design demands of a control systems are introduced.
Percentage of design: 30 %
