Abstract
An adaptive gain for voltage controller in fluxweakening control of permanent magnet synchronous motor (PMSM) is proposed. Based on voltage angle control scheme, voltage feedback controller can adjust control current locus and utilize the DC link voltage in flux-weakening region. The voltage controller is controlled using the difference between voltage reference magnitude and and a proper inverter limit value. The analysis of voltage controller is carried out, taking into account of modulation delay to issue the compensation performance with different voltage feedback gains from difference PMSM operating conditions. The adaptive gain of voltage controller is applied with forward feedback voltages and current vector to improve dynamic response with smaller voltage errors. The results of verification on a 7-kW PMSM platform demonstrate the effectiveness of the proposed method.

Full frame distilled prediction
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
