| 摘 要： | 研究了一种容错逆变器和在该逆变器不同桥臂故障时的永磁同步电动机矢量控制系统容错运行策略。分析了一种容错逆变器的工作原理,并由无中线引出的永磁同步电动机电流特性分析可以知道,三相定子电流之和等于零,通过两相定子电子就可以实现电机的电流控制。在此基础上提出了基于容错逆变器的永磁同步电动机矢量控制系统容错运行方案,该方案简单可行,并通过仿真实验验证了策略的正确性和有效性。

| Abstract: | Vector control for permanent-magnet synchronous motor(PMSM) drived by a fault-tolerant inverter was discussed.The operating principle of the fault-tolerant inverter was analysed.For PMSM without the middle wire,three phase currents can be controlled by controlling two phase currents of them randomly.A vector control scheme was proposed to drive PMSM based on the fault-tolerant inverter.Simulation results show the validity and the affectivity of the strategy,which is feasible and simple. |
