System
The experiments are set up with experimental panels in the profile frame. The Profi-CASSY is used to control this technical controlled system and to record and analyse the measured values.
Learning objectives
- Assessment of various stability criteria
- Optimisation with PC support
- Quality criteria and control surface
- Integral criteria: IAE, ISE, ITAE, ITSE
Function
One of the most important tasks of control engineering is the stability analysis and optimisation of control loops. The result determines the suitability of the control system for the intended application.
Method
The equipment includes student experiments in the laboratory with non-hazardous low voltage. Experimental procedures are carried out using a manual in printed or electronic form.
Target group
An internship aimed at further education programmes at technical colleges and technical universities.
Previous knowledge
- Knowledge of classical control engineering.
