| 摘 要： | 针对PID控制下的无刷直流电机(BLDCM)抗干扰能力差的问题,提出了Fuzzy-PID控制方法,该方法利用模糊逻辑控制器(FLC)在线调整PID的控制参数。在Matlab/Simulink环境下建立了基于Fuzzy-PID控制的无刷直流电机模型,并对转速误差进行归一化处理。仿真结果显示Fuzzy-PID控制与传统PID控制相比,在超调量、稳态时间、电流波动和转矩波动等方面有明显改善。

| Abstract: | In view of the problem of the poor anti-interference ability of the brushless DC motors （BLDCM） under the PID control, an fuzzy-PID control method is proposed, which adjusts the PID controller parameters online by the fuzzy logic contraller（FLC）. The model of BLDCM based on the Fuzzy-PID control is established in the Matlab/Simulink, and the normalization processing of the speed error is also conducted. The simulation results show that there is a significant improvement in the overshoot, steady-state time, current wave and torque fluctuation of the motor under Fuzzy-PID control compared with the traditional PID control. |
