The Pfix M4288 Series variable-frequency drive (VFD) controller is a self-contained field-mountable pump and drive controller designed as a supplement or alternative to PLC-based drive and pump ...

The PID controller design combines three control actions—proportional, integral and derivative—to compensate for errors between a measured process variable and a desired setpoint.

Significant research work has been carried out to improve the performance of closed loop response with PID controller so that it can be used for real time temperature control system using SCADA ...
