The work aims to design a web tension equalizer combined with fuzzy control and PID control, to improve the rolling system tension balance control performance of web press. With shaft-less driven multi-unit web press as an example, its working principle was introduced and winding tension mathematical model was established. On the basis of fuzzy control, adjustment factor was added to adjust the PID controller’s key parameters in real time, including proportion, integral and differential coefficient. The winding tension control system was built based on ARM controller STM32F103RC. The feasibility and effectiveness of the described method were verified by simulation and experiment. The experimental results showed that, after the improved fuzzy controller was adopted, its linear velocity and tension curve were smooth, the convergence speed was faster and the overshoot amount was small. The described control method can effectively restrain such problems as chattering caused by nonlinear factors. It can meet the requirements of printing process.
