Abstract
This paper describes the vibration suppression of a slung load which is carried by unmanned aerial vehicle (UAV), by tracking the vehicle to a vibration suppression trajectory. The trajectory is shaped in the frequency domain not to stimulate the normal mode of the UAV-load system. Since the frequency-domain design can explicitly handle constraints on acceleration and velocity of UAV, the resulting trajectory has time-suboptimality. The UAV-load system in a vertical plane is firstly modeled as DAEs and then the vibration suppression trajectory is designed using the natural frequency of load vibration and the vehicle constraints. Vibration suppression of the slung-load is verified in numerical simulations. The vibration control is finally implemented on ArduPilot, an open-source autopilot system.

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
