The presence of current harmonics stemming from the permanent magnet (PM) flux linkage harmonics poses a significant challenge in dual three-phase permanent magnet synchronous motor drives. In this paper, we propose an incremental model based on a bi-subspace virtual vector predictive current controller. Compared to the conventional model-based methods, the incremental model does not rely on prior knowledge of the PM flux linkage parameter, which can vary according to the operating conditions of the drive. Moreover, by incorporating a higher number of data steps in the prediction, the proposed incremental model ensures more accurate tracking of the reference currents and minimizes current harmonics induced by uncertainties in the PM flux linkage. Based on simulation results, this digest provides a comparison between the conventional and the incremental model-based bi-subspace virtual vector predictive current control methods.
