摘要：
The superior fault-tolerant capability is one of the most significant advantages of the multi-phase induction machines. The post-fault currents with the maximum torque were optimized of a fifteen-phase induction machine under asymmetrical fault condition. The corresponding fault-tolerant control strategy was proposed. The fault-tolerant control was based on the normal decoupling transformation and machine mathematical model, thus the machine parameters need not be recalculated and the reconfiguration of the controller was minimized. Different open-circuited faults of a 45kW prototype 15-phase induction machine were analyzed and tested. The good agreement between calculated and experimental results verifies the accuracy of the proposed fault-tolerant control. © 2018 Chin. Soc. for Elec. Eng.
