摘　　要：直线游标永磁(linear vernier permanent-magnet, LVPM)电机具有高功率密度和高推力密度的优点,并且其制造成本和维护成本低,非常适用于城市轨道交通。但采用传统的单逆变器驱动LVPM电机时,直流侧母线电压的利用率偏低。本文通过分析LVPM电机的数学模型,研究了开绕组LVPM电机的空间矢量脉宽调制(space vector pulse width modulation, SVPWM)策略,提出了一种目标矢量解耦控制策略,并搭建仿真平台进行了验证。仿真结果验证了上述方法的正确性。Linear vernier permanent-magnet(LVPM) motor has the advantages of high power density and high thrust density, and its low cost of manufacturing and maintenance is very suitable for the urban rail transit. However, when LVPM motor is driven by traditional single inverter, the utilization rate of DC bus voltage is low. By analyzing the mathematical model of LVPM motor, the space vector pulse width modulation(SVPWM) strategy of open-end winding LVPM motor was studied, a target vector decoupling control strategy was proposed, and a simulation platform was built to verify in this article. The simulation results verify the correctness of the above methods.
