关联时滞大系统的H_∞动态输出反馈控制——LMI方法

LMI Approach of H_∞-Dynamic Output Feedback Control for Large-Scale Interconnected Time-Delay Systems

基于线性矩阵不等式方法 ,针对具有N×N个任意未知常时滞的线性连续大系统 ,给出了整个关联时滞大系统的H∞ 动态输出反馈控制器存在的充分条件和设计方法 .由该方法设计出的控制器不但使闭环系统渐近稳定而且保证闭环系统从扰动输入到被控输出的传递函数的H∞ 范数小于给定的常数γ .

Based on LMI approach, the sufficient condition of the existence H ∞_output feedback controllers and the design procedure of large_scale interconnected systems with N×N unknown but constant delays are developed. The controllers presented make not only the closed_loop systems asymptotic stabi_ lity but also its transfer functional H ∞_ dynamic norm from disturbed input to controlled output less than a prescribed value
