Abstract
This paper presents a closed-loop vector control of an interior permanent magnet synchronous motor (IPMSM) drive incorporating two separate fuzzy logic controllers (FLCs). The first one is a Mamdani-type FLC which minimizes the developed torque ripple by varying online the hysteresis band of the PWM current controller. The second one is an FLC-based tuned proportional-integral (PI) controller where the PI controller actually serves as the primary speed controller and its 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. Thus, the proposed drive extends the operating speed limits for the motor and enables the appropriate use of the reluctance torque. The proposed IPMSM drive is also implemented in real time using DSP board DS1104 for a laboratory 5 HP motor. A performance comparison of the proposed IPMSM drive with conventional PI controller-based drive is provided. Simulation and experimental results demonstrate the better dynamic response in torque and speed for the proposed drive over a wide speed range.

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
