DESIGN FUZZY PID CONTROLLER FOR NONLINEAR SYSTEMS

Abstract

The Proportional, Integral, and Derivative (PID) controller is one of the most common controllers that is used by the industry. In nonlinear systems, the PID controller performance is weak unlike its performance with the linear systems which is very well. In this research, we are dealing with the PID parameters characterization. A fuzzy PID controller is proposed to enhance the performance of the conventional PID controller. The proposed controller is done by investigating a partial fuzzy PID controller and comparing it with classical PID. To distinguish the efficiency and robustness of the proposed controller for closed-loop systems. The proposed controller is tested for both linear and nonlinear systems with success with both. The results show that the proposed fuzzy PID controller is performing better than the classical PID controller.
