Abstract:
This paper proposes different tuning methods of PID controller for a level process. Four different controller tuning methods are taken. They are closed Ziegler Nicholos(ZN) method, Modified Ziegler Nicholos(M-ZN) method [without overshoot], Cohen Coon(CC) method and Model Predictive Control method(MPC). These four methods are compared and listed out in a table. Among these MPC method is the best tuning method of PID for a level process.
