Tuned Proportional-Integral-Derivative (PID) Control System

Abstract

The research work is simply based on the comparison between the PID controller and the tuned PID control system. It is highly desired that the PID controller be tuned in order to remove the oscillation experienced by the PID controller, that is, the overshoot, the delay, and the undershoot. The intelligence (Fuzzy) tuning method/technique is applied in this work, to achieve the comparison aimed at. The developed idea was based on the process of heat control intelligently, using the IF-THEN rules of Fuzzy logic. Results obtained from simulation showed that the Untuned (Block) PID controller has a settling time of 59.38 Sec with a percentage overshoot of 40% and a percentage undershoot of 13.33%. While the Tuned PID has a settling time of 50 Sec with a percentage overshoot of 8% and percentage undershoot of 0.00%. This showed that the Tuned PID gave a better performance compared to the Untuned PID.
