Characterization of Rate Dependent Hysteresis of Piezoceramic Actuators
Bibliographic record
Abstract
A generalized Prandtl-Ishlinskii model is proposed for characterizing the rate dependent hysteresis behavior of piezoceramic actuator. Rate dependent play operator is formulated and integrated to the Prandtl-Ishlinskii model together with dynamic density function to model hysteresis as a function of rate of change of the input. The fundamental properties of the proposed rate dependent operators are discussed. Laboratory experiments were performed to characterize the rate dependent hysteresis behavior of a piezoceramic actuator under excitation in the 0.1 to 200 Hz frequency range. The measured data were used to demonstrate validity of the proposed generalized model. The comparisons suggest that the proposed rate dependent operator and density functions allow for accurate characterization of the rate dependent hysteresis of piezoceramic actuator under dynamically varying inputs.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
