【Abstract】 In order to solve the problem of poor fault tolerance in traditional fault tolerant control methods, a fault-tolerant control method for permanent magnet synchronous motor based on coupling inductance is proposed. Through the high torque running state of the permanent magnet synchronous motor and the flux linkage equations of different axes of the motor, the coupling inductance flux model is constructed by using the self-induction flux and flux generated by cross-coupling. According to a great extent amplitude output torque, the propulsion system is given larger output power and speed range, and the amplitude and phase of the residual normal current vector of the motor after fault can be adjusted reasonably, so that the magnetomotive force of each phase winding of the motor that can operate normally is equal to that of the motor that operates normally Through the design constraints, the only solution is obtained to realize fault-tolerant control. The simulation results show that the fault-tolerant control method is effective, effective, and feasible for PMSM.更多还原
