The Electric Vehicle Drive System Considering Current Sensor Fault

This paper proposes an algorithm of electric vehicle drive system when any current sensor fault. Reconstruct rough stator current by decomposing the DC current. Test whether any sensor fault by comparing the rough reconstructions and measured stator currents.Switch to the reconstructed stator current after corrected from the fault current when a stator sensor faults. Switch to the reconstructed DC current from the fault current when the DC sensor faults. Simulation result verifies the effectiveness of detecting the fault and keeping electric vehicle operation normal.
