Comparison of Flow Process Values for Different PID Controller Techniques

Abstract

The main objective of this paper is to find the best and suitable controller that can be applied for a flow process in a real system. The flow process is done in a cylindrical tank of cascade system. The search of PID controller is done by the steps of acquiring transfer function from the real time open loop response and invoking it to the various tuning techniques of PID controller results in the proportional, integral and derivative values for our process. The calculated values are implemented in an Matrix Laboratory Environment using simulation which reaches the conclusion of desired controller based on the time domain specifications (Peak time, Rise time, Settling time) and performance error criteria (ITAE, IAE, ISE, MSE).

Keywords: PID controller, flow process, ITAE, IAE, ISE, MSE
