Abstract
The active vibration suppression of a single flexible link manipulator using a piezoelectric actuator is investigated. For this purpose, a finite element (FE) model is developed for the modal and transient analysis of a cantilever beam and a flexible link manipulator. A proportional control strategy is employed in a FE model to adjust the voltage applied to the piezoelectric actuator so as to control vibration. For the flexible link manipulator, it is shown that the vibration is well suppressed during and at the end of a manoeuvre by locating the piezoelectric actuator at the optimum location. The effect of the value of the controller gain on the vibration behaviour of the system is investigated and the optimum controller gain is found using two main evaluation criteria; these are contribution of dominant frequencies in response and the norms of vibration amplitudes.

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
