Research on Fuzzy PID-Internal Model Control System of Permanent Magnet Synchronous Motor

在取消离合器和同步器的纯电动汽车电传动系统中,PMSM作为纯电动汽车驱动源在电动汽车的变速过程中起着断开动力和主动同步的作用。在PMSM控制系统中,通过内模控制算法对电流环PI控制参数进行了整定,在传统的转速环PID的基础上建立了模糊控制规则,并在matlab/simulink仿真环境中搭建了PMSM的仿真模型,并进行了仿真实验。仿真实验结果表明,通过内模PI控制和模糊PID控制算法可以使PMSM控制系统获得更好的调速性能和转矩输出性能,提高了控制系统的鲁棒性。

In the electric drive system of the pure electric vehicle without the clutch and synchronizer,PMSM,as the driving source of the pure electric vehicle,plays the role of driving power and active synchronization in the transmission of the electric vehicle.In the control System of PMSM,the PI control parameters of the current loop are obtaineded through internal model control algorithm,and,the fuzzy control rules are established on the basis of the traditional speed loop PID,and the MATLAB simulation model of PMSM is builted in simulation environment.The simulation experiment is carried out.The simulation results show that the internal model PI control and fuzzy PID control algorithm can make the control system of PMSM achieve better speed regulation performance and torque output performance,and improve the robustness of the control system.
