Abstract
In this paper, a robust pitch rate control design for longitudinal aircraft motion based on μ-synthesis is presented. A Linear Fractional Transformation (LFT) uncertainty model is first derived for robust synthesis. The uncertainty dealt with is of parametric nature and represents the variations of weight and center of gravity in the aircraft models. A controller is then developed and tested on the full longitudinal model of the Challenger 604 aircraft provided by Bombardier Aerospace Inc. The model includes both short-period and phugoïd modes of the aircraft, the stick, the actuator and the sensors. It is shown that the controller guarantees desired performance with predicted Level 1 handling qualities under varying weight and center of gravity locations.

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
