In this work, the effects of open-switch faults over speed sensor fault-tolerant scheme for electric traction drive are analyzed. The fault-tolerant scheme uses a sliding mode observer to generates a fault diagnostic signal and to estimates the rotor speed of an induction motor. Through simulation results, the effects of faults in an electric drive and their interaction on the dynamic performance of an electric vehicle are analyzed.
