Speed Control of DC Motor Using Fuzzy Fractional order PID Controller

Abstract

7- Abstract DC Motors are widely used in industries for various purposes. Many situations request changes in the speed of the DC Motor, and this makes necessity to develop a method to effectively control the speed of DC motor. In this research, speed of DC motor is controlled via fuzzy frictional order PID (FFOPID) controller. The fuzzy control law is implemented determine the value of the frictional order PID (FOPID) controller. Three parameters (kp, ki, kd) of FOPID controller are determined through fuzzy approach, while the other two parameters (y,;1) are tuned based on try and error approach. Simulation work is conducted to verify the effectiveness of the FFOPID controller. Furthermore, the proposed controller is benchmarked with the FOPID and PID controller to show the perfonnance of FFOPID controller. It’s found that, FFOPID controller achieve faster response than both FOPID and PID controllers. Moreover, the FOPID controller has less transient response than FFOPID and PID controllers. PID controller has the less response in tem of speed and transient response. Moreover proposed the disturbance of DC motor, the DC motor with model reference controller with a small effect of the disturbance at the midpoint of the simulation, at step time is (Ssec), The FOPID controller has less overshoot than the FFOPID and PID controller.
