N2 - This article proposes a novel predefined-time sliding mode predictive current control (PDO-SMPCC+HDO) technique to simultaneously enhance disturbance rejection and dynamic response in surface-mounted permanent magnet synchronous motor (SPMSM) drives. Specifically, a composite disturbance predictive model incorporating both slowly varying disturbance and sixth current harmonic disturbance is developed. A predefined-time reaching law (PTRL) and corresponding sliding mode disturbance observer are proposed to effectively estimate the slowly varying disturbance, while the sixth harmonic disturbance is estimated using a frequency-domain harmonic disturbance observer with a specially designed filter. A PTRL-based reference trajectory is defined for the PDO-SMPCC+HDO cost function to adjust the current approach trajectory. Finally, an integrated predictive control scheme is developed by minimizing the cost function. Experimental results on an SPMSM test bench verify the superior disturbance suppression and tracking capabilities of the proposed strategy.
