In order to improve the control motor speed of steady state and dynamic characteristics because of brushless dc motor has highly nonlinear characteristics. Design of a self-adaptive Fuzzy-PID control for the brushless dc motor, and with traditional PID control compared by simulink simulation of MATLAB/Simulink platform. The results show that self-adaptive Fuzzy-PID control improve the speed of response ability, reduce the overshoot and torque ripple, which has high robustness.
