In order to improve the shock resistance and excitation fault-tolerant control level of ship propulsion motors during variable speed operation, a method for shock resistant excitation fault-tolerant control of ship propulsion motors during variable speed operation is proposed. This method first clarifies the correlation characteristics between current and magnetomotive force during normal operation by deriving the expressions for six phase sine current, fundamental magnetomotive force of each phase, and synthetic magnetomotive force formula. A mathematical model of magnetomotive force for a six phase permanent magnet synchronous motor is constructed, and the current and electromotive force data of the ship's propulsion motor are obtained through this model. Based on the propulsion motor current data, a phase loss excitation fault detection mechanism is designed. The faulty phase is determined by detecting the phase current, and neutral compensation is used to inject zero sequence current to resist current impact. Finally, a voltage correction equation and modulation duty cycle are used in coordination to achieve variable speed operation excitation fault-tolerant control and ensure magnetic flux stability under faults. The experiment shows that the calculated values of the established magnetomotive force model have a high linear correlation with the true values; Fault detection can accurately identify single-phase and combined phase loss faults; The midline compensation has a current surge suppression rate of 41.9%–44.8%; After fault-tolerant control, the magnetic flux trajectory of the motor was restored to a circular shape, verifying the effectiveness of this method in improving fault-tolerant control performance and system stability.
