Abstract
This article presents a new way to achieve reduced-order controllers using an integrated controller-plant dynamics approach. The proposed method combines the controller and plant dynamics to achieve specific overall control functionalities. The method is applied to a grid-connected inverter that conventionally uses second-order proportional-resonant (PR) and proportional-integrating (PI) transfer functions. The proposed approach replaces a third-order PR+PI function with a first-order PI function without compromising its features. The approach is to integrate the dynamics of the inverter and its output filter with the PI function to achieve a PR functionality. The proposed approach not only obviates the computational and digital implementation challenges pertaining to the PR compensators, it also results in a generally more robust and stable operation of the inverter in practical grid conditions. Detailed theoretical analysis, simulations, comparisons, and laboratory experiments are presented to elucidate various aspects of the proposed method.

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
