Piezoelectric ceramic actuators have wide application prospects in precision positioning and measurement technology, but its hysteresis characteristics cause a lot of restrictions to their applications. To solve this problem, this paper summary the hysteresis characteristic of piezoelectric ceramics, and collect the data through the experiment, analyze and research the piezoelectric ceramic hysteresis curves at different excitation signal effect, and the fitting curve is got based on the experimental data in order to establish hysteresis model of piezoelectric ceramic actuators by using of the curve fitting toolbox of MATLAB. Then the inverse model is obtained and the inverse compensation feed-forward control algorithm is proposed. The experiment results show that the piezoelectric ceramic actuators meet the basic linear relationship between the input voltage signal and the output displacement, and eliminate hysteresis nonlinear of the piezoelectric actuators.
