Abstract:According to the vehicle permanent magnet synchronous motor drive system features,this paper proposes the new speed sensorless vecor control strategy of permanent magnet synchronous motor based on model reference adaptive of the stator current for electric vehicle. The reference?model?and?adjustable model of the current are constructed, and the difference between the two model outputs is adjusted by the adaptive mechanism and the adaptive rate to adjust the parameters of the model in real time, so as to realize the parameter identification of the speed and position of the motor. In the design environment of Matlab/Simulink, the simulation study and result analysis of the system shows that the new speed sensorless vecor control strategy of permanent magnet synchronous motor for electric vehicle based on model reference adaptive has a good effect on motor parameter identification and dynamic,static performance.
