Abstract：To ensure the vehicle’s normal operation after a failure in the speed sensor, based on using the existing sensors, this paper has a research on speed sensorless vector control system. The Γ-1 model of induction motor is introduced, based on which the extended Kalman filter (EKF) observer and speed estimation problem are studied. A speed sensorless control system is constructed, which has been proved the feasibility via experiments.
