Dynamic and Positioning Performances of Linear Electromechanical Actuator

摘要

This paper presents the dynamic characteristics and the proposed positioning performance of the system which were investigated experimentally. In this research, we developed the positioning system and we evaluated positioning accuracy. The developed system uses a servo motor for motion actuation. In this paper, we focused on studying the dependency of the positioning error–elementary errors–the position of the conducting element for the mechanism of the transformation of the rotation translation movement, representatively the mechanism screw–screwdriver and on emphasizing the practical consequences in the field of design, regulation and exploitation of the correct identification of all the initial errors in the structure of the mechanism, their character and the selection for an ultimate calculus of these which are of a real practical importance.
