A Low-Cost, High-Fidelity Processor-in-the Loop Platform: For Rapid Prototyping of Power Electronics Circuits and Motor Drives
Bibliographic record
Abstract
With the rising complexity in digital control algorithms for power electronics (PE) systems, prototype design and software control testing procedures have become increasingly time-consuming and costly. To minimize time to market and improve software quality assurance, this article presents a lowcost, safe, and reliable processor-in-the-loop (PIL) concept for rapid prototyping. PIL provides a framework to verify the actual control algorithm on a dedicated microcontroller that controls plant simulation in the software environment (SE). The corresponding communication approaches, constituting blocks and preliminary results, are presented in detail. The accuracy and fidelity of the PIL platform is validated through software-in-the-loop (SIL) simulations. It is shown that PIL leverages the embedded code generation features of the SE, which enables controller design and testing through minimal modifications to generated code and eliminates the need for real hardware during development, therefore removing safety concerns and any risks of damaging the expensive hardware. The presented approach also helps identify coding errors, casting errors, and platform-specific configuration errors even before the actual test setup is functional.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
