The present disclosure provides a multi-excitation-source axial-flux permanent-magnet motor with partitioned, hierarchical, and variable poles, and a variable-condition driving control system. The motor mainly includes a main magnetic pole and an auxiliary magnetic pole. The main magnetic pole is responsible for providing a main air gap flux and is connected in series with a dual-stator magnetic circuit. The auxiliary magnetic pole is responsible for adjusting an air gap field and is connected in parallel with the dual-stator magnetic circuit. Magnetic fluxes of the main magnetic pole and the auxiliary magnetic pole together constitute the air gap field. The present disclosure can control a flux path of the auxiliary magnetic pole by controlling the magnitude of a current applied to a field winding, thereby adjusting an air gap flux, expanding a speed range of the motor, and achieving variable-condition operation of the motor.

A unified open-circuit fault-tolerant control method for a vector control (VC) drive system and a direct torque control (DTC) drive system of a five-phase permanent magnet fault-tolerant motor are provided. The control method adopts a unified open-circuit fault-tolerant control strategy. The unified open-circuit fault-tolerant control strategy includes: obtaining a predetermined torque, obtaining predetermined direct-axis and quadrature-axis voltages, analyzing a fault-tolerant mechanism to obtain fault-tolerant currents, obtaining winding phase voltages in a fault mode based on the fault-tolerant mechanism, and obtaining fault-tolerant voltages based on a back-electromagnetic force (EMF). The unified open-circuit fault-tolerant control strategy suitable for the VC drive system and the DTC drive system is proposed based on chaotic pulse width modulation (CPWM). The control method essentially reveals the fault-tolerant mechanism, and solves the problem of variable and complicated fault-tolerant control schemes corresponding to various basic control algorithms.
