Good performance of the electromagnetic torque is dependent upon reliable operation ofthe feedback sensors such as position sensors, current sensors and voltage sensors. In event ofsensor failures, HEVs may accept permanently reduced drive performance and even bringabout fatal traffic accidents. In practical applications, the most common failure of controlsystems is sensor faults. Therefore, it is also necessary to develop a torque control system ofinduction motor for HEVs with sensor failures.
