一种卷绕传输系统的建模、辨识与混合灵敏度H_∞鲁棒控制

Modeling, Identification and Mixed-sensitivity H_∞ Robust Control of a Web Winding System

介绍了一个由开卷轴、拖动轴、收卷轴和两个张力感应器组成的织物卷绕传输系统的建模及模型的参数辨识,并采用混合灵敏度多变量H_∞鲁棒控制来改善系统的控制性能,减少织物张力与速度之间的耦和。

A web transport system including an unwinder, a tractor, a winder and two load cell has been modeled from the physical laws, and the model parameters are identified using optimization methods. A mixed-sensitivity multivariable H_∞ robust control is used to improve the performances and reduces the coupling between web tension and velocity in this paper.
