Modeling and Simulating of the Tension Control System of Printing Press

Web tension is in close relation with the printing speed and quality. And it is the most important factor in printing. Therefore, to improve the printing quality, to control the web tension accurately is of the most important. The control system developed much faster in overseas. But the research on web tension has big gap in our national printing press. A set of integral method and theory of web tension control was developed. And the math model of tension control system was established and the simulation experiment was applied. The result showed that the new control structure is of good reliability. It has important meaning to improve accuracy of tension control system of the domestic web press.
