FLC based tuned PI controller for wide speed range operation of IPMSM drive
Bibliographic record
Abstract
This paper presents a fuzzy logic controller (FLC) based tuned proportional-integral (PI) controller for interior permanent magnet synchronous motor (IPMSM) drive. The PI controller serves as the primary speed controller whose gains are tuned by a novel Sugeno type FLC. Thus, the limitations of traditional PI controllers are avoided and the performance of the drive system is improved. A flux controller is also incorporated in such a way that both torque and flux of the motor can be controlled while maintaining current and voltage constraints. The flux controller is designed based on maximum-torque-per-ampere (MTPA) operation below the rated speed and flux weakening operation above the rated speed. Thus the proposed drive extends the operating speed limits for the motor and enables the appropriate use of the reluctance torque. A performance comparison of the proposed IPMSM drive with conventional PI controller based drive is provided. Simulation results demonstrate the better dynamic response of the proposed drive over a wide speed range.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
