Abstract
In this research we presents a compared to different study of speed control system technique for a BLDC motor. The Control modules that have been designed is one of several types of traditional control and adaptive. First, the controller is designed according to conventional PID controller. Secondly, Fuzzy control systems that are basically robust have been designed with seven membership functions, two inputs and one output. Finally, the optimal fuzzy self-tuning PID controller (STFPID) is then designed with automatically tuning PID controller parameters (KP,KI& KD), were the fuzzy logic technique is used to adjust all gain value of PID controller. The gain value of PID are the output signal of the fuzzy controller. The performances of the speed response with three controllers are compared. The results of simulation shown that the designed STFPID controller Achieve best performance of the BLDC motor, a perfect tracking of speed give low rise time , less maximum overshoot ,settling time , less steady state error and give best response versus PID and Fuzzy Logic technique. The ability technique to achieving the target speed and robustness to eliminate the load disturbances are one of the important aspects of this study.
