BLDC motor speed servo system based on novel P-fuzzy self-adaptive PID control
Based on the mathematical model of BLDC motor, a novel P-fuzzy self-adaptive PID intelligent method is proposed for controlling the speed servo system. In the BLDC motor speed control system, the current hysteresis is implemented in the current loop, in the speed loop the P and fuzzy self-adaptive PID hybrid control scheme is applied. Organically combined the blocks, a test was performed on a timing system of double close loops with current hysteresis and speed fuzzy control. Simulation result indicated that the improved accuracy of control system, half-shortened response time,minished overshoot, fine robustness and self-adapting are obviously shown to outperform the ordinary proportional-integral, differential (PID) control. The validity of the model was verified and thus a new way was provided for further research of the motor.
