Abstract:
 Abstract: Multiphase induction machine drives are suitable in the application of electric vehicle due to
their advantages over conventional three phase drives: high power under low voltage,less torque pulsation,
higher efficiency,fault tolerance operation,etc. Strategies for fault-tolerant control of a 5-phase
motor were analyzed,based on the principle of maintaining the same magnetic motive force( MMF) after
the fault occurrence. And the interaction between 1st and 3rd MMF under fault-tolerance operation was investigated.
Proportional resonant regulator was adopted to resolve the passive impact of torque ripple and
low efficiency caused by hysteresis control,which can achieve zero steady-state error even in the stationary
phase frame,because of its large gain at the target electrical frequency. A five-phase induction motor
drive system with low DC link was constructed,and experimental results verify the analysis of the fault
tolerance control strategies under open phases.
