Non integer order PID controller tuning using grey wolf optimization method for Sea Water Reverse Osmosis Desalination process
The optimal integer order and fractional order controller setting are designed for the Sea Water Reverse Osmosis Desalination plant model. The Controller settings are tuned using the grey wolf optimization method to minimize the time absolute integrated error values. The interaction measures are analyzed for the design of pairing in the multiloop controller settings. The comparative simulation response are demonstrated between the integer order PID and non integer order PID controller. The simulation results show the improvement of closed loop performance with the non integer order controller settings. It is observed that Improved grey wolf optimization based FOPID provides slightly improved performance in the controller tuning compared to PID controller.
