POSITION CONTROL FOR (PPDCV) USING PID & FUZZY SUPERVISORY CONTROLLER

Pilot Proportional Directional Control Valve (PPDCV) is mostly used for control the Cement Industries. Accuracy and precision without any disturbance for position control of the actuator is the goal for engineering applications. This paper presents explain mathematical model for (PPDCV) and position controller for hydraulic actuator that move the clinker cooler.PID controller with fixed parameters is used for position control with normal condition. In our system, the parameters of the system may be varying with time, pressure source of the system. It may cause disturbance. However, PID controllers are good for position control with transient response and reduce steady state error. It could not reduce disturbance. To eliminate the disturbance problem, Fuzzy supervisory control (FSC) is used in this work with special adjustment. FSC will tune PID parameters online and can handle with parameters variation. The simulation experiment is performed using Matlab and Simulink.
