Dual-loop geometric-based control of buck converters
Bibliographic record
Abstract
Voltage mode and dual-loop current-mode linear controllers are widely used in buck converters due to their simple implementation and fixed frequency PWM operation. While the dynamic response can be improved by pushing the control bandwidth, lower stability margins may lead to unexpected peak deviations, leading to failures due to magnetic saturations or excessive overshoot. A dual-loop geometric compensator is introduced in this work by combining state-plane analysis with traditional linear controllers. The proposed geometric voltage loop tightly controls the time-domain evolution of the state variables, providing a reliable transient response by following a desired geometrical path to reach the target steady state operating point. Straight line and circular trajectories are implemented resulting in an outstanding, well defined, and reliable transient behaviour. Experimental results of dual-loop geometric-based controlled 50W platform validate the proposed control concept and highlight the strong contribution to the applied field made by this innovative controller.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
