A novel wing-rock control approach using hysteresis compensation
Bibliographic record
Abstract
The paper addresses the control issue for wing-rock motion of slender delta wings. Wing-rock motion is a self-excited limit-cycle oscillation at high angles of attack. Experiments shown that hysteresis provides clues about where the motion is being driven and damped. Generally, the effects of hysteresis for moment coefficient vs. roll angle can be treated as a combination of phase and magnitude distortion. To suppress the wing-rock, hysteresis compensator, so-called phaser, is adopted to eliminate this hysteresis. The phaser, an inverse phase function of the hysteresis, can be approximated by a linear filter. Furthermore, a variable phaser control scheme is designed to handle multi-loop hysteresis. The final synthesis scheme combines the variable phaser and P control to accelerate the wing-rock attenuation. The effectiveness of the proposed scheme is demonstrated by the control of wing rock at different angles of attack.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
