摘　　要：双三相电机系统在发生缺相故障后无需任何硬件或软件重构即可以维持运行,因其安全性和经济性备受工业界青睐。然而,只有在完成故障诊断和定位,并重构控制策略后,才能实现满意的容错性能。同时,故障诊断和存储不同故障情况下的控制策略也增加了算法的复杂性。为解决这些问题,提出一种双三相电机系统开路故障被动容错控制策略,通过修改谐波子空间电流控制器,使其能够同时应用于正常运行和容错运行工况。仿真结果表明,提出的被动容错控制策略能够实现从正常运行到容错运行的平稳过渡,无需额外的硬件和软件重构。Dual three-phase motor systems can continue to operate after a phase loss without hardware or software reconfiguration,valued for safety and economy.However,satisfactory fault tolerance is achieved only after diagnosis,localization,and control strategy reconfiguration,which adds complexity to the algorithm.To address these issues,a passive fault-tolerant control strategy for open-circuit faults in dual three-phase motor systems is proposed.By adjusting the harmonic subspace current controller,it can be applied to both normal and fault-tolerant operations.Simulation results show that the strategy enables a smooth transition from normal to fault-tolerant operation without additional hardware or software reconfiguration.
