| Abstract: | The piezoelectric actuators are widely used in the field of micro displacement positioning, but its hysteretic nonlinear property has serious effect on the positioning accuracy of piezoelectric actuators.In this paper,various kinds of methods of improving the hysteretic nonlinear property of piezoelectric actuator have been introduced.The cubic spline interpolation method and least square curve fitting method have been proposed to achieve the precise positioning of piezoelectric actuators and improve the hysteretic nonlinear property of piezoelectric ceramic actuators.The experimental results have shown that the proposed methods can make the positioning error of piezoelectric actuator down to 5%. |
