Data for: High-Speed Preisach Hysteresis Model Identification Method of Piezoelectric Actuators Based on Mapping Graph

This dataset for hysteresis identification of the piezoelectric actuator was obtained by applying specific voltage signals to the actuator, resulting in multiple input-output data sets. The input data represents the original input voltage without voltage amplification and ranges from 0 to 5V. The output data corresponds to the displacement signals captured by the displacement sensor. Additionally, this dataset includes the identified parameters of the Preisach hysteresis model associated with the research work mentioned in the paper.\\
