Abstract
Implementation of AC drives insensitive to parameter variation is a challenge which interests many researchers in the field of high performance drives. In the case of drives controlled by the indirect rotor flux orientated control method (IRFOC), the rotor time-constant (/spl tau//sub r/=R/sub r//L/sub r/) exerts a dominant role in the loss of dynamic performances and its variation results in creation of an undesirable coupling between flux and torque of the machine. This paper presents a new scheme for online estimation of this parameter using measurements of motor accessible variables (voltages, currents and speed). This scheme is tested by simulation in the MATLAB/SIMULINK environment and also real-time implemented on a TMS320C31 digital signal processor. Both simulation and experimental results are presented.

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
