Abstract
A tool for generating a self-excited oscillations for underactuated mechanical systems by means of a variable structure controller is proposed. The design procedure allows to find the explicit expressions of the controller gain parameters in terms of the desired frequency and amplitude through describing function (DF) method. Necessary conditions for orbital asymptotic stability of linear systems are derived via a modification of the Loeb criteria. The identification and compensation method yields an exact linearization of the original nonlinear system avoiding imperfections on oscillations characteristics. Performance issue of a self-excited system, applied to a Furuta pendulum, is illustrated by simulations.

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
