Abstract
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.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
