Abstract
Abstract Control of balancing current is important for the safety of battery cells and active cell balancing (ACB) power electronics. This paper presents a method, based on quantitative feedback theory (QFT), for robust control of balancing current despite uncertainties, which exist in the battery cells' and power electronics' dynamical models. A remarkable feature of QFT is its interactive graphical design environment, which gives useful insights for the selection of desired robust stability and performance specifications, controller structure, and parameters tuning. Without loss of generality, this paper describes the QFT‐based balancing current robust control system design for a forward‐converter‐based ACB. This paper also presents an average model of the forward‐converter‐based ACB circuit, operating in more than two modes; a case that has not been addressed in literatures. The effectiveness of the proposed QFT‐based balancing current robust control system is evaluated experimentally.

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
