摘　　要：提出一种内置式永磁同步电机(InteriorPermanent Magnet Synchronous Motor,IPMSM)的最大转矩电流比(Maximum Torque Per Ampere,MTPA)模型预测控制(Model Predictive Control,MPC)方法。方法通过MTPA控制,建立了电机电磁转矩参考值与定子电流d、q轴分量之间的关系。在瞬态时,上述方法与传统的单矢量MPC相同,以d、q轴电流的跟踪误差作为代价函数,保持了传统的模型预测控制动态响应快的特点;在稳态时,采用双矢量MPC,减小了转矩脉动,改善了电机的稳态控制性能。仿真结果表明,与i_(d)=0的MPC相比,给出的控制策略动态响应快,稳态转矩脉动小,铜损耗低。In this paper,a maximum torque per ampere(Maximum Torque Per Ampere,MTPA)dual vector model predictive control method for IPMSM is proposed.The method establishes the relationship between the motor electromagnetic torque reference value and the d and q axis components of the stator current through MTPA control.During the transient state,the method is the same as the traditional single-vector model predictive control,with the tracking error of the d-axis and q-axis currents as the cost function,maintaining the features of the fast dynamic response of traditional model predictive control;During the steady state,the dual-vector model predictive control is used to reduce the torque ripple and improve the steady-state control performance of the motor.The simulation results show that compared with the MPC with i_(d)=0,the proposed control strategy has faster dynamic response,smaller steadystate torque ripple and lower copper loss.
