摘　　要：考虑到内置式永磁同步电动机磁阻转矩利用率问题,选用最大转矩电流比控制策略,对其电流给定和转矩给定两种控制方式进行研究,并建立了相应的矢量控制模型进行对比分析。仿真结果表明,相比于电流给定,转矩给定的最大转矩电流比矢量控制系统响应速度较快,调速稳定,鲁棒性更好。Considering the reluctance torque utilization of Interior Permanent Magnet Synchronous Motor(IPMSM),the maximum torque per ampere control strategy(MTPA)is selected.The two control methods of current setpoint and torque setpoint are studied,and the corresponding vector control model is established for comparison and analysis.The simulation results show that the maximum torque per ampere vector control system with torque setpoint has faster response,more stable speed regulation and better robustness compared with current setpoint.
