N2 - This paper proposes a novel concept to eliminate the digital delay effect on rotor position for the traditional two-step finite control set model predictive current control (FCS-MPCC) method used in the PMSMs. Specifically, that the digital delay affects the position, and further the prediction accuracy is discussed firstly, posing the necessity of compensating the position used for control. Then, a speed-prediction-based linear compensation method which takes the speed shift trend into account is proposed to eliminate the digital delay impact on position, which is conducive to the control performance. Finally, simulation is conducted on a three-phase PMSM to validate the proposed strategy in comparison with the traditional two-step FCS-MPCC.
