Abstract
H/sub 2/ (LQG), weighted-H/sub 2/ and H/sub /spl infin// techniques are used to establish a nominal performance baseline for the vertical acceleration control of a B-52 aircraft model with flexibilities. The aircraft is assumed to be subjected to severe wind gusts causing undesirable vertical motion. The purpose of the controllers is to reduce the transient peak loads on the airplane caused by the gust. Our designs account for the flexible modes of the aircraft model. We use the Dryden gust power spectral density model to guide the performance specifications and control designs, as well as for time-domain simulations. Motivation for the use of an H/sub /spl infin// performance specification is given in terms of a new interpretation of the Dryden model. Both weighted-H/sub 2/ and H/sub /spl infin// optimal controllers are shown to reduce dramatically the effect of wind gust on the aircraft vertical acceleration when compared to the regular H/sub 2/ controller.

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
