LEVEL CONTROL WITH PID CONTROLLERS: EXPLORING SIGNIFICANT TUNING TECHNIQUES FOR IMPLEMENTATION IN INDUSTRIAL PROCESSES
Keywords:
PID controller, level control, Ziegler-NicholsAbstract
Proportional-Integral-Derivative (PID) controllers are widely used in industrial process control applications due to their simplicity and effectiveness. This study explores significant tuning techniques for the implementation of PID controllers in level control applications for industrial processes. A simulation model of a level control process was developed using the MATLAB/Simulink environment. The PID controller was tuned using three different tuning methods: Ziegler-Nichols (ZN) method, Cohen-Coon (CC) method, and Internal Model Control (IMC) method. The performance of the PID controller was evaluated based on several performance metrics, and the simulation results showed that the performance of the PID controller was significantly influenced by the tuning method used. The Internal Model Control method was found to provide the best overall performance, with minimal overshoot, fast rise time, and settling time.
