摘　　要：为改善永磁同步电机(PMSM:Permanent Magnet Synchronous Motor)模型预测控制系统中较高的转矩脉动与磁链脉动,通过学习永磁同步电机的基本构造和控制方法,设计了一种对占空比与电压矢量进行同步调节的模型预测控制系统方案。通过选择某一取样时间的最优预期电压矢量和作用时间,加上当前取样时间的最优预期电压矢量和作用时间,对采样时间的占空比系数实现调整。通过对仿真模型进行对比分析,验证了该方法对提升永磁同步电机控制性能的可行性和有效性。In order to improve the torque ripple and flux ripple in the model predictive control system of PMSM(Permanent Magnet Synchronous Motor),a control system scheme is designed by learning the basic structure and control methods of PMSM.The scheme adjusts the duty cycle and voltage vector synchronously.The optimal expected voltage vector and action time at a certain sampling time are selected,and the optimal expected voltage vector and action time at the current sampling time are added to adjust the duty cycle coefficient of the sampling time.The feasibility and effectiveness of this method in improving the control performance of PMSM are verified by comparative analysis of the simulation model.
