This paper introduces a new method to track the saliency of a PMSM motor fed by a four-leg inverter in case of a single phase open circuit fault through measuring the dynamic current response of the motor line currents due the IGBT switching actions. In the case of a single phase open circuit fault, a fault-tolerant control strategy that includes taking appropriate actions to control the two remaining...
This paper introduces a new method to track the saliency of motor fed by a multilevel inverter through measuring the dynamic current response of the motor line currents due the IGBT switching actions. The method uses only the fundamental PWM waveform (i.e there is no modification to the operation of the multilevel inverter) similar to the fundamental PWM method proposed for a 2-level inverter. Simulation...
