This paper focus on the problem of robust stabilization of a class of uncertain large-scale 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 technique 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 time-variant.Finally,a numerical example is given to demonstrate the validity of the results.
