| 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. |
