Electronic Controlled Systems

E6.3.4.1

System

The experiments are set up with experiment plates in profile frames. The controlled system or control circuit are activated with the Profi-CASSY and the relevant measurement values recorded.

Educational objectives

Get familiar with the basic principles of controllers
Setpoint and disturbance control
Handle analysis and simulation software

Function
The setup facilitates experiments on a wide variety of levels: ranging from the basics to university-level learning. It investigates the transfer components in the time range and the behaviour of the controlled systems formed by them. Digital adjusters for controller parameters and system time constants facilitate simple, intuitive operation of devices with higher precision. This allows for fast, reproducible, and targeted experimentation. Continuous and discontinuous controller designs are available to choose from. The Profi-CASSY interface is ideally equipped to support the use of graphic analysis methods (e.g. using the tangent method) and facilitates experiments with modern interface controllers and computer-aided control technology. For more in-depth experimentation and for simulations, it is recommended that you also use the WinFACT software.

The equipment set incorporates student experiments which can be carried out in a laboratory safely using safety extra-low voltage. Experiment instructions are contained in a manual in either printed or digital form.

Add-ons
The following sets are recommended for further learning:
