Global uniform asymptotic stabilization of a class of uncertain large scale systems with decentralized control

Based on a new theoretical result on global uniform asymptotic stability (GUAS), we investigate GUAS of a class of uncertain large scale systems. Under the assumptions that the uncertainties and interconnections of the systems satisfy the matching conditions and are bounded by known functions in states, decentralized controls are proposed to guarantee GUAS for the resulting systems whose isolated nominal subsystems are GUAS in the standard sense.
