Modeling and control method for color register system in electronic shaft gravure printing machine acceleration process

Abstract

The invention relates to a modeling method for a color register system in the electronic shaft gravure printing machine acceleration process. The modeling method comprises the following steps that (1) error open-loop data of the color register system in the electronic shaft gravure printing machine acceleration process are collected; (2) filtering processing is carried out on the collected error open-loop data, so that a mathematical model of the color register system in the electronic shaft gravure printing machine constant-speed process is obtained; (3) the error open-loop data generated by the color register system of an electronic shaft gravure printing machine in the acceleration process are regarded as knowable disturbance, the mathematical model of the color register system in the electronic shaft gravure printing machine constant-speed process is corrected according to the principle of linear superposition, and therefore a dynamic model of the color register system in the electronic shaft gravure printing machine acceleration process is obtained. According to the modeling method for the color register system in the electronic shaft gravure printing machine acceleration process, obtaining of good control performance serves as the purpose, and the obtained model can eliminate inconsistency of all units in an actual system.

Description

technical field [0001] The invention relates to the field of printing, in particular to a method for modeling and controlling a color registration system in the acceleration process of an electronic axis gravure printing machine. Background technique [0002] The printing and manufacturing industry has always been a pillar industry of the country. For color printing products, its quality depends not only on the printing process, but also on the performance of color registration control. Whether the color registration accuracy of printed products can be controlled within the range required by the industry mainly depends on the performance of the color registration control system in the printing process. [0003] After the gravure printing machine is started, it includes several processes, including pre-registration, low-speed overprinting, acceleration and high-speed printing, etc. For pre-registration, low-speed registration and high-speed printing, there are related liter...
