Abstract: In order to solve the problems of giving full play to the brushless DC motor (BLDCM）performance ,intelligent control method was investigated ,for control method is extremely important to the performance .After the analysis of the BLDCM mathematical model, the BLDCM control system model was established in Matlab R2008a+Simulink.The improved singleneutron PID control method used in the speed loop was presented to improve the systems responding, stability and robustness. Based on the correctness of BLDCM model that was proved by the running result, the BLDCM control system using the improved singleneutron PID control algorithm was evaluated by simulation. By contrasting the simulation results of PID control method and the improved singleneutron PID control algorithm，the comparison result shows that it has better control performance by using the improved singleneutron PID control algorithm in the BLDCM control system.
