摘要
The superior fault-tolerant capability is one of the most significant advantages of multiphase induction machines. In this paper, post-fault currents are optimized for a 15-phase induction machine supplied by non-sinusoidal voltage with third-order harmonic injection. To obtain the maximum smooth torque matched the propeller load, a fault-tolerant control scheme is proposed through analyzing the couple effect between fundamental and third-order harmonic rotating MMFs. The proposed control uses the pre-fault decoupling transformation matrix, thus the change of the controller is minimized. Different open-circuited faults experiments of a 45-kW prototype 15-phase induction machine verifies the validity of the proposed fault-tolerant control.
