Abstract
This paper investigates piezoelectric actuator placement optimization on a rectangular plate structure and the vibration control of the structure. In the first part, an actuator placement optimization method is developed based on maximizing the controllability grammian. It is then implemented using Structuring Analysis in ANSYS Finite Element Analysis Package and Genetic Algorithm. In the second part, a filtered-x LMS-based multi-channel adaptive control is used to suppress vibration response of the plate. Numerical simulations are performed in suppressing tri-sinusoidal response at three points of the plates and the results show the control algorithm is efficient and robust in reducing the plate’s vibration. The results also demonstrate that the developed actuator placement optimization method is effective to reduce the energy required for achieving significant vibration reduction.

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
