Abstract
In this paper, a fault-tolerant control design that can gain schedule with the airspeed is developed for a flexible aircraft with actuator saturation and stuck control surface faults. First, a flexible aircraft model that captures the coupling between rigid-body motions and flexible modes is presented. Then, a linear parameter-varying fault-tolerant controller featuring a proportional and integral structure is designed for a stuck control surface scenario, with control gains solved from a set of set-invariant conditions represented by linear matrix inequalities. The controller, which gain schedules with the airspeed, is able to eliminate the effects of stuck faults on the system output while minimizing the effects on other system states and guaranteeing no closed-loop performance degradation caused by actuator saturation. Finally, the effectiveness of the proposed design is demonstrated on an aircraft model with high-aspect-ratio wings in numerical simulations.

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
