Digital Control System

We offer Digital COntrol Syste 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 8085 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 16 levels each. Further, the user may write his own programs to implement additional algorithms and study their responses.
