Fault detection and fault tole rant control of interturn short circuit of double redundancy motor

Abstract This paper presents the robust detection of interturn short circuit fault double redundant permanent magnet synchronous motor. In static coordinate system and dq-axis system, mathematical model state is established. Further, residual signal current caused by turn-to-turn predicted using Luenberger observer. Next, marker phase are obtained processing signal. Finally, processor performs excision faulty phases hardware reconfiguration, thus allowing fault-tolerant operation The simulation results show effectiveness tolerance
