Abstract
In this paper, a Grid Search Method (GSM) with a Field Oriented Control (FOC) is presented to determine the optimal Proportional-Integral (PI) controller gain parameters for the speed control of an induction motor. This technique is useful in finding the optimal controller gain (proportional and integral) in a closed loop system. The GSM is used to obtain gains required for the adaptive PI by seeking the optimal local minimum of a squared speed error function. The results show that the GSM is very efficient, and gives stable convergence characteristics. It has a good track record of robustness under load variation, fast dynamic response, and high precision in tracking desired speed. Furthermore, the control system, based on the GSM-PI algorithm in FOC for induction motors, can be readily implemented for occasions of frequent load changing, such as in industrial applications.

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
