Abstract
Presented in this paper are the results of tests involving high-speed closed-loop control of a virtual permanent magnet synchronous motor (PMSM) drive implemented on a field-programmable gate array (FPGA) card, connected to an external controller. Three types of motor drive models are actually implemented on the FPGA card of the RT-LAB based real-time simulator used: a Park (d-q) model along with two different implementations of finite element analysis (FEA) based models. The first FEA model, previously published, is an FPGA implementation of a FEA model with an inductance calculation routine running on an associated CPU of the real-time simulator. The second FEA model has its inductance routine coded in the FPGA. One of the main objectives of the paper will be to compare the performance of the two FEA models. By virtue of the faster, FPGA-located, inductance routine update rate of the new model, it is expected that its precision at very high speed will be greater than the previous model, which was shown to be limited to 400 Hz electric frequency.

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
