Fault Tolerant Adjustable Speed Motor Drives for Automotive Applications

Abstract

Adjustable speed motor drives, and in particular vector-controlled AC motor drives, are being increasingly used as mission-critical components in a variety of high-performance automotive applications [1]. However, proper operation of the closed-loop control system depends on reliable operation of the electromechanical actuator, power electronic power processor, control circuitry, and feedback sensors. In the event of sensor failures, it is desirable that the AC adjustable speed motor system continues to operate, even if under a diminished performance capacity. This is especially important in the high-impact automotive applications where even limp-back operation is preferred over no operation.
