Closed Loop Brightness Control

E6.2.1.1

System
Modern technology without control engineering cannot be imagined. Practical examples such as a heating control are familiar to everybody. In the following experiments, various controls from the two-point regulator to the PID controller are presented and investigated.

Function
The aim of the experiments is the computer-aided realization of closed control loops. With PID- and 2-Point controllers the power of an incandescent lamp is controlled, whose brightness is measured using a photo resistor.
