摘　　要：在负载突变工况下,准确地模拟永磁同步电机负载转矩是建立转矩前馈补偿控制仿真模型的关键。运用谐波分析方法,研究了突变负载转矩工况下q轴电流各次谐波随负载转矩的变化规律,提出了仿真模型中负载模拟准确性的验证方法,并给出了电机控制系统的仿真计算和实验结果。仿真与实测结果相近,证明所介绍的仿真建模方法是正确的。An analysis and accuracy verification method of sudden change load torque simulation was proposed, in permanent magnet synchronous motor （ PMSM）, with a torque pre compensation control strategy. The change regulation of the q axis current with the sudden change load torque was analyzed , with harmonics analysis method. The accuracy verification method of the load torque simulation was studied. The simulated and experimental resuhs validate the correctness of the simulation model.
