Abstract
Summary This article copes with the adaptive fixed‐time funnel control problem for a class of nonlinear systems with actuator faults. To deal with the difficulties due to actuator faults, which include both lock‐in‐place and loss‐of‐effectiveness models, an adaptive fault‐tolerant control scheme is proposed. By introducing the fuzzy logic system and backstepping technique, an adaptive fixed‐time controller is developed to ensure that the tracking error converges into a pre‐specified performance funnel within a fixed time, which is independent on the initial state, and in the meantime, the controlled closed‐loop system remains semi‐global fixed‐time bounded stable and all the signals are bounded. Simulation results verify the proposed approach.

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
