Abstract
A proportional-integral and fuzzy-logic speed controllers operating in indirect field-orientation are designed and compared experimentally in this paper, using a 2-HP 3-phase induction machine drive. The speed tracking capability of the two controllers are compared under no-load and various load conditions with different reference speeds. The performances of the drive are also evaluated under sudden electric and mechanical disturbances. Simulation and DSP experimental results on a 2HP 230 V/5.8 A Delta-connected 3-phase induction machine show that the performance of the fuzzy-logic controller is more satisfactory than that of the proportional-integral controller in a number of cases and, hence, can be a suitable candidate for high-performance 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
