Abstract

The invention discloses a method for designing a precision control device for a piezoelectric ceramic actuator and a precision control system. The design method comprises the steps of using a Bouc-wenmodel to construct a hysteresis nonlinear model of the piezoelectric ceramic actuator; solving an inverse function of the hysteresis nonlinear model to obtain a hysteresis compensator; constructing alinear dynamics model of the piezoelectric ceramic actuator by using parameters alpha1, alpha2, ..., and alphan and b0, b1, ..., and bm identified by an ARX function of a Matlab system identificationtoolbox; adopting the phase or order of the linear dynamics model to select a learning filter, and constructing an iterative learning controller according to the learning filter; connecting the hysteresis compensator with the iterative learning controller to form the precision control device for the piezoelectric ceramic actuator.

Description

technical field [0001] The invention relates to the technical field of motion control and precision manufacturing, and specifically relates to a design method and a precision control system of a piezoelectric ceramic actuator precision control device. Background technique [0002] With the continuous development of MEMS (micro electro mechanical system) technology, people's exploration and research in the microscopic field continue to deepen. In many application fields, such as precision machining, optical fiber communication, material science, etc., the requirements for the accuracy of the driver are gradually deepening. The traditional motor driver can no longer meet the requirements of the above fields due to its large inertia, slow response and low precision. As a kind of intelligent material, piezoelectric ceramics have the advantages of fast response, large driving force, high precision, and good stability, and are widely used in micro-nano positioning and driving syst...
