Abstract
This paper presents the development of high fidelity real-time model of a permanent magnet synchronous motor (PMSM) drive, to be used in hardware-in-the-loop (HIL) application. The PMSM model is based on a finite-element analysis (FEA) method and implemented on an FPGA chip. The motor inductances and flux maps are computed from the JMAG-RT finite element analysis software. A 3-phase IGBT inverter drives the PMSM machine. Both models are designed in Simulink using the Xilinx Blockset and then automatically compiled and loaded on the FPGA using the RT-LAB real-time simulation platform. The complete PMSM drive model runs with an equivalent 10 nanosecond time step and has a latency of 300 ns (PMSM machine and inverter), with a total HIL delay from external PWM inputs to analog outputs with 1 microsecond settling time on the FPGA of just 1.3 microseconds.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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
