摘要：

To improve the stability of hub drive electric vehicle, the fault-tolerant control algorithm of five-phase permanent-magnet synchronous motor is studied in this paper. A Model predicate current control (MPCC) algorithm with pre-selection and duty cycle is designed for 5-phase PMSHM in different operations. The model of 5-phase PMSHM in fault operations is discussed and coordinate transformation matrix in single-fault, adjacent two phases fault, and nonadjacent two phases fault operations are deduced, respectively. The proposed fault-tolerant model predictive current control can deal with a difference of current fault operations, effectively. Thus, the stability of the hub drive system is improved.
