Model-based method is used to achieve position sensorless control of the IPMSM drive system when the motor runs at middle or high speed. The model method estimates the rotor position by the back-EMF or the flux linkage model of the fundamental frequency excitation. Since the rotor saliency and the additional test signal are not needed, the rotor position information can be estimated only by the motor model. This model-based method is relatively simple to implement, so the method is widely used in the vector control system for sensorless IPMSM drive.
