| 摘 要： | 针对复卷机在复卷过程中卷径变化以及加减速时对纸幅张力的影响,以放卷张力控制系统为研究对象,在深入分析复卷机张力控制系统放卷部分受力情况的基础上,推导了放卷张力系统的数学模型,提出利用变频器内部功能实现直接张力和间接张力相结合的复合张力控制、卷径实时计算等方法,用直接张力控制精度,用间接张力提高系统的抗扰动能力,以满足复卷时恒张力控制要求.

| Abstract: | In view of the influence of the rewinder on the sheet tension when the winding radius varies and the rewinder accelerates/decelerates,studied the unwinding tension control system,thoroughly analyzed the tension of the unwinding part,and proposed a mathematic model of the unwinding tension system.Also put forward methods such as using the internal functions of the vector transducer for the combined direct and indirect tension control and winding radius real-time calculation.It proposed to control the precisi... |
