N2 - The deadbeat predictive current control (DPCC) exhibits strong dynamic performance in the current control of permanent magnet synchronous motor (PMSM), whereas the performance of the traditional DPCC depends on the accuracy of model parameters to a great extent. To cope with this problem, parameter sensitivity of the traditional DPCC has been analyzed in detail, with a disturbance observation compensation method proposed to improve the robustness of the current control of PMSM. Furthermore, a method of non-singular terminal sliding mode disturbance observer (NTSMDO) which employs a novel reaching law, combined with the DPCC is put forward to enhance the parameters robustness of the current loop. A harmonic compensation (HC) term has been added to the output of the current control for ignoring the harmonic electromagnetic process in the mathematical model of the PMSM to further promote the performance of the current loop control. Simulation and experimental results demonstrate that the proposed method offers robustness against parameters mismatch and control precision compared with the traditional DPCC.
