Proper operation of vector-controlled induction motor drives over the entire speed range critically depends on reliable operation of the feedback sensors. In the event of sensor failures, it is desirable that the induction motor system continue to operate, even if under a diminished performance capacity. This paper describes the development of a fault-tolerant control system for an induction motor with automatic controller reconfiguration. The system adaptively reorganizes itself in the event of sensor loss or sensor recovery to sustain the best control performance given the complement of remaining sensors. Theoretical and experimental results are presented.
