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id =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.
Abstract
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 e-lectromagnetic 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 re-sponse 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 id=0,the proposed control strategy has faster dynamic response,smaller steady-state torque ripple and lower copper loss.
