Abstract
This paper describes a new approach to control a single-link flexible manipulator by using smart actuators. A combined PD feedback for rigid motion control and the distributed piezoelectric polymer (PVDF) actuator for vibration damping is investigated using a Lyapunov approach. The PVDF actuator is designed independently from joint velocity of the manipulator, which allows high speed motions. Most of the current PVDF actuators are A-type schemes depending on measurement of the tip angular velocity of the beam, a signal not readily available. This paper is the first to show that the available linear velocity (at the tip) feedback control, L-type scheme, can also guarantee the stability of the system. The L-type scheme does not lead to control problems caused by mode truncation, and is more efficient to suppress the dominant mode vibration of the beam. Simulation results confirm these theoretical predictions.

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
