摘　　要：针对时变的满足一定匹配条件的不确定关联时滞大系统,利用自适应界化技术,给出了设计分散镇定控制器的自适应的方法.其特点是在假设中系统不确定项是有界的,但界是未知的,且在关联项存在时变时滞的情况下证明了闭环自适应系统的渐近稳定性.最后举例说明了该方法的有效性.This paper focus on the problem of robust stabilization of a class of uncertain largescale interconnected time-delay systems, the uncertainties satisfy some certain matching conditions, they are normly bounded, but the bounds of uncertainties are unknown in controller design. The adaptive bounding tecbnique is proposed to estimate the unknown bounds. A class of decentralized memoryless state feedback controllers is constructed, which make the closed- loop system is asymptotically stable. The time-delay presented in the interconnectiOns is timevariant. Finally, a numerical example is given to demonstrate the validity of the results.
