【Abstract】 A novel method of rotor speed estimator based on various research of speed sensorless was presented.It finds a solution to deal with the altering parameters for not only the stator resistance in the low speed but also the stator transient inductance in the magnetic field weakening.Rectifying parameters is used to improve the accuracy of estimators.Finally,simulations have been performed to show the stability of the proposed estimators.更多还原
