五相永磁（5Ph）电机的容错控制问题近年来得到了广泛的研究，但对故障条件下的解耦建模却讨论较少。本文研究了5Ph PM电机在单相断路故障下的解耦模型，并在此基础上将磁场定向控制（FOC）应用于电机。该模型基于与正常情况相同的单相断路故障时基本磁动势（MMF）和反电动势（EMF）保持值的概念，并在基本旋转空间保持相等的转矩方程。然而，由于气隙磁链的三次谐波和系统的不确定性，输出转矩仍然存在一定的噪声，为了解决这些干扰，在速度环中提出了滑模控制（SMC）来改善速度性能。所提出的SMC包含一个PI控制器和一个抖振项，因此可以很容易地调谐。通过瞬态有限元分析（FEA）对解耦模型进行了验证，并给出了进一步的实验结果来验证所提控制策略的有效性。
Fault-tolerant control of a five-phase (5Ph) permanent magnet (PM) motor has been recently widely studied, however decoupled modeling under faulty conditions is discussed in less details. In this paper, decoupled model of the 5Ph PM motor under single-phase open fault is investigated and based on the proposed model field oriented control (FOC) is applied to the motor. The proposed model is based on the concept of preserving values of fundamental magnetic motive force (MMF) and back electromotive force (EMF) under single-phase open fault, the same as in healthy case, along with keeping equal torque equation at fundamental rotating space. Nevertheless, the output torque still presents some noises due to third harmonics of air-gap flux and system uncertainties, and to cope with those disturbances, sliding mode control (SMC) is proposed in the speed loop to improve the speed performance. The proposed SMC contains a PI controller and a chattering term, and thus it can be easily tuned. The decoupled model is verified by transient finite element analysis finite element analysis (FEA) and further experiment results are presented to confirm the effectiveness of the proposed control strategy.
