Abstract
This paper presents a FPGA-based virtual motor drive system featuring two Permanent Magnet Synchronous Machine (PMSM) drives made with two-level IGBT/GTO inverters model with full fault capability. The inverters are implemented on the FPGA with a nodal solver, using floating point arithmetic, and support individual component faults, like a single IGBT open fault, as well as other non-standard modes, like cases with no IGBT gate signals and natural rectification. The motor model can be either linear d-q models or Finite Element Analysis models from JMAG-RT. The virtual motor drives are implemented on a Virtex-6 FPGA card and have a total latency near 1μs from the IGBT gate signal capture at Digital Inputs to motor currents at Analog Outputs and are therefore well adapted for HIL tests with high-speed machine with either PWM (up to 100 kHz) or hysteretic current control. Finally, the paper presents experimental accuracy validation made by a TIER-1 supplier for hybrid electric vehicle in Japan.

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
