摘　　要：在永磁无刷直流电机调速系统中,采用了自适应模糊PID控制器。建立了永磁无刷直流电机的数学模型,并以此进行转速和电流双闭环无刷直流电机调速系统控制。通过自适应模糊PID控制器在线调整PID控制器的三个参数,完善了PID控制器的性能。仿真和试验结果都表明,该方法比经典PID控制器具有更快的动态响应和更小的超调。For BLDCM speed regulating system, the parameter＇ s self-adaptive fuzzy PID controller was con- structed. A BLDCM simulation model was built, based on it a control system with close loops of speed and current was experimented. This controller improves the performance of the whole system by adjusting certain parameters of the self-adaptive Fuzzy-PID controller online. This strategy controller is proved to have faster dynamic andsmaller overshoot compared to PID controller both in simulation and experiment.
