摘　　要：介绍了永磁同步电机(PMSM)在d-q坐标系下的数学模型。针对永磁同步电机传统PID系数固定不变的缺陷,采用变系数PID控制方式,根据模糊控制规则实时调整PID控制器的系数,来增强永磁同步电机整体的抗干扰能力,内环采用PI控制,实时跟踪电流变化,提高系统跟踪性能。使用Matlab/Simulink建立仿真模型并进行了仿真实验,仿真结果表明,变系数PID控制方式比传统PID控制方式有更好的抗干扰能力和跟踪能力,为实际应用提供了参考。The mathematical model of permanent magnet synchronous motor(PMSM) in d?q coordinate system is intro?duced. To overcome the defect of fixed PID coefficients of PMSM,the variable?coefficient PID control method is used to adjustthe coefficients of PID controller in real time according to the fuzzy rules,so as to enhance the entire anti?interference ability ofPMSM. The PI control is adopted in the inner loop of the controller to track the change of current in real time,and improve thesystem tracking performance. The simulation model was established with Matlab/Simulink. The simulation results show that thevariable?coefficient PID control method is superior to the traditional PID control method in the aspects of anti?interference andtracking abilities.
