Tension control systems are commonly used in our daily life and business, such as VHS, tape rewinder, recorder, tape-making procedure, etc. In these systems, it is clear that the quality of products and the performance of systems are determined by tension and velocity control of the moving web. Too small tension in the winding process will make the web flagging. Oppositely, too large tension will make the web overreach, leading to permanent distortion. Besides, the slow winding rate will make efficiency down and the fast winding rate will amplify the vibration amplitude of moving web so that it will be hard to control.
In this paper, the web-fed machine modeling and control are presented. SMC (Sliding Mode Control) method is employed to control the tension and velocity of the moving web. The robustness of SMC method can be suitable for more uncertainties and external disturbances. It makes the operation range more flexible, and upgrades the system performance and the system stability. Further, it improves the manufacture efficiency and the product quality of the web-fed machine.
