摘　　要：设计了一种用于永磁同步电机转速闭环控制的模糊自整定PID控制策略，能够根据当前电机转速的偏差对PID参数进行实时的调整，克服了常规PID控制因参数固定而无法适应被控系统实际状态变化的不足。在Simulink环境中，建立了永磁同步电机转速闭环矢量控制系统的模型，并通过仿真和实验结果，证明了本文所提出的模糊自整定PID控制，能够取得比常规PID控制更好的控制效果。PID regula In order to improve the performance of conventional PID control method, a fuzzy self-tuning tor is designed for the close-loop control of motor speed because of its merits including good adaptability and high precision. This regulator is able to adjust the PID parameters automatically to fit different system status, according to the error of motor speed. A simulation model of PMSM drive system is established in MATLAB/Simulink and the simulation result shows that fuzzy self-tuning PID control has better performance compared with regular PID control
