Abstract
This paper presents a decentralized adaptive fuzzy approximation design to achieve attitude tracking control for formation flying in the presence of external disturbances and actuator faults. A nonsingular fast terminal sliding mode controller that is based on consensus theory is designed for distributed cooperative attitude synchronization. It solves synchronization issues between multiple satellites by information topology. In the proposed control scheme, a fuzzy logic system (FLS) is introduced to approximate unknown individual satellite attitude dynamics due to actuator faults. In order to achieve fault management without the involvement of ground-station operators, the proposed control laws do not require an explicit fault detection and isolation mechanism. Numerical simulation results including actuator dynamics and initial condition uncertainties show that the proposed strategy with FLS can compensate for a fault. The system continues to operate after wheel faults, and the closed-loop distributed tracking control system is stochastically stable.

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
