摘要：
Multi-phase BLDC (Brushless DC) motors with high efficiency and power density are widely used in electric propulsion systems such as electric vehicles, submarines, and electric ships. It is important that the multi-phase motors used in these applications operate stably without generating large torque ripple in various fault scenarios. In this paper, three fault-tolerant control methods are compared to reduce torque ripple by controlling the magnitude and phase angle of healthy phase currents under open circuit failure applied to remove the second harmonic component of torque, which has a large influence on torque ripple, is compared. The proposed fault-tolerant control methods were validated through HIL simulation of a 12-phase BLDC motor.
