摘　　要：为了进一步提高电机控制的动态性能,减小电流和磁链脉动,结合磁场定向控制和直接转矩控制的优点,研究了一种多电压矢量的永磁同步电机模型预测控制策略。利用电流状态方程和二阶欧拉法对定子电流进行预测,通过控制目标函数得到最佳的开关状态。搭建仿真平台,比较不同控制方式下的转速响应及定子电流、磁链脉动。仿真结果表明,该控制策略响应速度快,电流和磁链脉动小,取得了良好的控制效果。To improve the dynamic performance of motor control and reduce the current and flux ripple,combined with the advantages of field oriented control and direct torque control,a predictive control model of PMSM based on multi voltage vector was proposed. Using current state equations and two order Euler method predict the stator current,and the optimal switching state was obtained by the objective function. The simulation platform was built to compare the speed response,the current and flux ripple under different control method. Simulation results show that the proposed control strategy has the advantages of fast response,small current,flux ripple and good control effect.
