摘要：在Matlab/Simulink平台上建立了无刷直流电机驱动系统的动态模型，提出了无刷直流电机的模糊自适应|PI控制，根据偏差和偏差变化率，在线修改PI的积分时间常数和比例系数，控制PWM输出信号，获得了很好的控制效果。仿真结果表明，这种算法较之传统的PI控制方法，系统的超调量减小，没有振荡现象，且响应快。

Abstract: The brushless DC motor drive system has been modeled  in Matlab/Simulink and a fuzzy self|turning PI parameters control strategy of BLDC motor has been presented. Based on the error and error derivative of velocity, the percentage and integrate factor were modified online and PWM output signals were produced. As seen form the results of simulation, a satisfied effect has been achieved. This method help to reduce the over|regulating and eliminate oscillation, and the respondence is fast.
Key words: brushless DC motor; simulation; self|tuning PI; fuzzy control
