Abstract

fetched live from OpenAlex

Autonomous aerobatic flight for fixed-wing aerial vehicles is studied. This paper proposes an uncertainty and disturbance estimator (UDE) based controller that attenuates the special effect of model uncertainty and external disturbances during the aerobatic harrier maneuver using a novel targeted filtering structure. Knowledge of the disturbance frequency content and the undisturbed system dynamics are used in filter design to improve disturbance rejection compared with standard UDE-based controllers with low-pass filtering structures. The controller performance is validated on a simulated model of a vehicle performing the low-speed, high angle-of-attack harrier aerobatic maneuver.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
