【正文】 el. Simulation results prove the effectiveness of the PSObased parameter selftuning fuzzy PID control， and verify the method is better than traditional PID control and adaptive fuzzy PID the former control algorithm. Also the new method has advantages， such as faster response， smaller overshoot，stability and strong tracking performance. This will not only verify the reasonableness of the theory of the control algorithm， also can shorten the development cycle and save cost. Provide a good development methodology for the development of brushless DC motor control algorithms.
