摘　　要：薄膜双向拉伸生产线的核心之一是张力控制,它直接决定了生产出的薄膜的质量。针对双工位收卷转塔在换卷作业的过程中由于转塔翻转产生的薄膜张力变化影响成品膜质量的问题,提出一种前馈速度补偿策略。该策略通过直接对换卷作业过程中转塔翻转对薄膜产生的叠加速度进行计算,并根据计算的叠加速度关系式设计一个基于前馈-PID的张力控制系统,并通过与传统PID控制器进行仿真实验对比。结果表明,该系统具有良好效果,提高了薄膜的得率。Tension control is a critical technology in the production line of biaxially stretched film,as it directly influences the quality of the final product.To address the issue of tension fluctuations in thin films caused by tower rotation during roll changes—an effect that compromises finished film quality—this paper introduces a feedforward speed compensation strategy.This approach involves calculating the cumulative speed imparted to the film due to tower rotation during roll transitions and designing a tension control system based on a feedforward-PID framework informed by this calculated relationship.Comparative simulation experiments demonstrate that this system outperforms traditional PID controllers,yielding significant improvements in film production efficiency.
