Abstract
Due to the complexity and inconstancy of the space environment, accurate mathematical models for spacecraft rendezvous are difficult to retrieve, which consequently complicates the control tasks. In this paper, a linearized time-varying plant model with consideration of the external perturbations is developed to approximate the spacecraft rendezvous in near-circular orbits. In order to achieve the robust stability with optimal performance cost, a partially independent control scheme is proposed, which consists of a robust anti-windup controller for the in-plane motion and a H ∞ controller for the out-of-plane motion. The effectiveness and advantages of the partially independent control scheme are verified by comparing with other control schemes in a numerical example.

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
