In order to implement model reference adaptive system online parameter identification for PMSM, reference model and adjustable model was constructed, and with the output difference of the two model through adaptive device, the parameters for identifying were obtained by adjustable model adaptive rate regulating, eventually making the parameters for identifying in the adjustable model converge to a correct value, the parameters was obtained. Simulation and experimental validated that with the method, stator resistance, stator inductance, the flux of the permanent magnet could be identified accurately in real time.
