Nonlinear Characteristics Measurement of Piezoelectric Ceramics Actuator Based on LabVIEW

摘要

Piezoelectric ceramics actuator has wide application prospects in precision positioning and measurement technology, but its nonlinear characteristics cause a lot of restrictions to their applications. To solve this problem, the experimental data are collected to establish nonlinear model of piezoelectric ceramics actuators. Firstly, the input and output data are collected with LabVIEW. And then, the characteristics is analyzed to establish the nonlinear model for the piezoelectric ceramics actuator, finally, the hysteresis characteristic description of piezoelectric ceramics is got based on the experimental data filtered.
