Decentralized Robust Control of Interconnected Large-Scale System Based on H∞ Theory
-
摘要: 基于H∞理论提出了关联大系统分散鲁棒控制的一种新的设计方法.得到的控制器不但 使闭环系统渐近稳定,而且能使闭环系统从扰动输入到被控输出的传递矩阵的H∞范数小于 某个给定的扰动变小常数,并对系统参数的不确定性具有鲁棒性.Abstract: In this paper, a new design method for decentralized robust control of large-scale interconnected system by H∞ theory is presented. The controller obtained not only asymptotically stabilizes the closed-loop system but also makes the H∞ norm of the closed-loop transfer function matrix from disturbance input to controlled outputs be less than a given disturbance-attenuation constant and is robust for plant parameter uncertainty.
