Contents I. Introduction
Compared to traditional three-phase motors, multi-phase motor is widely used in conditions with high reliability requirements for motors such as airplanes and warships, due to its features of high efficiency and reliability [1]–[3]. Researchers have proposed various fault-tolerant control methods for one phase open-circuit faults in electric motors, aiming at different targets, such as ensuring minimum copper loss method [4]–[6] or limiting post fault torque ripple [7]–[9]. These methods optimize the amplitude and phase of normal phase currents during the motor’s phase-fault operation. By employing hysteresis current control, motor achieves fault-tolerant and disturbance-free operation, leading to smooth torque output [10].
