To improve the strong dependence of predictive control parameters on finite control set (FCS) models, an improved robust FCS predictive current control (FCS-MPCC) algorithm for permanent magnet synchronous motor (PMSM) drive systems is proposed. First, the problems of complex calculation and inaccurate selection of voltage vectors in traditional FCS-MPCC are analyzed, and an extended voltage vector-based MPCC (EV2-MPCC) based on the deadbeat principle is proposed to improve the steady-state performance of FCS-MPCC and also improve the anti-disturbance performance of the system. Second, the performance of PMSM under parameter mismatch is analyzed, and a sliding mode observer (SMO)-based stator current and disturbance observer is proposed. The observed disturbance term is used to compensate the reference voltage term for quickly selecting the optimal voltage vector, and the estimated current replaces the traditional predicted current. This method further improves the robustness of EV2-MPCC. Finally, the experimental results prove the effectiveness of the scheme.
