This study presents an advanced algorithm for controlling the web longitude and tension of nonlinear roll-to-roll systems in the form of a cascade structure. Parameter variation and disturbance attenuation problems are addressed systematically. The features of this article are divided into two parts. First, active damping terms are injected to stabilize the system nonlinear dynamics so that the first-order closed-loop transfer functions are obtained for each loop via pole-zero cancelation. Second, disturbance observers are introduced to ensure the performance recovery property by attenuating the disturbances from the model-plant mismatches. The closed-loop system is numerically emulated using MATLAB/Simulink to show the effectiveness of the proposed technique.

这项研究提出了一种先进的算法，以级联结构的形式控制非线性卷对卷系统的幅材经度和张力。系统地解决了参数变化和干扰衰减问题。本文的功能分为两个部分。首先，注入主动阻尼项以稳定系统非线性动力学，以便通过零极点抵消为每个环路获得一阶闭环传递函数。其次，引入了扰动观测器，以通过减轻来自模型工厂不匹配的扰动来确保性能恢复性能。使用MATLAB / Simulink对闭环系统进行了数值模拟，以证明所提出技术的有效性。
