复卷机退纸卷张力控制的动态补偿分析

The analysis of dynamic compensation about the rewinder's tension control

本文通过对复卷机退纸卷张力控制进行探讨分析了张力产生的原因,建立退纸卷的动态转矩平衡方程,根据卷径和线速度大小的变化,调速装置通过组态完成卷径计算和电枢电流给定计算,并对其动态过程进行电流补偿,保持纸幅张力大小不变。

The paper analyzes the procreant cause of the web tension and sets up the dynamic torque equation of the unloading scroll according to the research of the rewinder＇s scroll tension control. With the change of scroll diameter and velocity, the timing device sets the scroll diameter calculation and armature current calculation by configuration., and compensates current for the dynamic pro- cess. By this way we can keep the web tension constant.
