N2 - In terms of the conventional predictive current control system divergence problem caused by the motor's inductance error, this paper proposes two first-order extended state observers (ESO) to observe the d-axis and q-axis disturbance, introduces the observed disturbance into the conventional predictive current control to construct a robust predictive current control, and analyses the stability condition of the proposed method. The ESO can estimate the general disturbance including the parameter uncertainties and sensor noise, so that the robust predictive current control system can compensate the disturbance to counteract the influence of the motor's inductance error and restrain system divergence. Simulation results verify the validity of the proposed strategy.
