Research On Gravure Package Printing's Chromatography Control Based On Shaftless Transmission Technology

In the paper, the subject of Research on Gravure Package Printing's Chromatography Control based on Shaftless Transmission Technology is selected as the thesis, which researches in shaftless system's isochronous and coordination control with high speed. The paper analyses profoundly in the feather of shaftless gravure package printing. According to the system's characters, the paper makes exploratory study in aberration elimination and synchronization coordination, and puts forward innovatively a new control method based on the thought of deviation-coupled control; meanwhile paper gets good results according to simulation.Design of shaftelss chromatography system is a complex topic; the main reason is that the research on shaftless printing system is a comprehensive topic, which is corcern with some aspects'coordination. As shaftelss printing system is different with traditional system, which should coordinate aberration elimination and synchronization coordination control, so it is a complex topic.The paper chooses a new registering processing method based on positioning mode with analysis in features of shaftless printing system and registering control, and it transforms the aberration into position track adding to the axes. Taking into account of the tension and printing material's change on the impact of aberration, the paper makes the detecting aberration optimum model. According to the feather of printing system and the servo motor's operation, the paper makes use of trigonometric function acceleration and deceleration curve to making the detecting aberration into track, then the system gets the smooth position, speed and acceleration curve, avoiding the affect of collision to the system in the calibration process.As for system of synchronization and coordination control, according to the feather of all axes'mutual constraints and interaction and strong coupling, the paper introducts the thought of deviation-coupled control in coupled synchronization control methods, and approaches innovatively multi-grade coupling aberration as aberration given. And then, the paper combinates the given and aberration elimination strategy as the system's strategy, which enhances the efficiency of synchronization and strengthens the ability of inhibition to electrical disturbances and aberration changes. In the aspect of aberration processing, the paper uses the control methods having good performance of tracking control-Backstepping control and Directive adaptive-fuzzy control, then combines them to the thought of deviation-coupled control. It formats the strategy that is Backstepping control and Directive adaptive-fuzzy control based on the the thought of deviation-coupled control. Through simulation proving, it can not only realize the global synchronization but also inhibits the disturbance of load and parameters change on the whole synchronization system. And the designes controller makes the system owns the character of robust, which realizes integrated design object of aberration registering and synchronization control at meantime.
