N2 - In the case of low switching frequency application for sensorless permanent magnet synchronous motor (PMSM) drive system, the time delay of the digital controller is more significant and deteriorates the system performance. In this paper, the high frequency square-wave voltage injection method is adopted to estimate the rotor position and a hybrid control strategy is proposed combining a bilinear transformation based deadbeat controller and a nonlinear extended state observer (ESO). The deadbeat controller can improve the accuracy of the predicted current and compensate the inherent time delay as well. The ESO can compensate the dynamic disturbance of the system and predict the feedback value of the current. Simulation and experimental results proved the effectiveness of the proposed method.
