Digital Control System

Description

We offer Digital Control System usefull for control laboratory experiment. In the present unit a second order transfer function, simulated with operational amplifiers and passive components, has been chosen as the process to be controlled. This results in a well behaved and near perfect linear process which gives a highly predictable performance. The digital controller consists of a ***5 based microprocessor kit with analog-to-digital and digital-to-analog interface. Software supplied with the system resides in a 8K EPROM. This consists of P, PI and PID algorithms in which the three gains may be selected out of *6 levels each. Further, the user may write his own programs to implement additional algorithms and study their responses.

Highlights of the equipment:

• Digital Controller implementation on mP-kit
• Simple Op-amp based analog plant
• CRO display of response
• Design and test new algorithms

• Identification of the controlled process
