This paper investigates the quadratic stability problem of a class of uncertain largescale systems composed of several similar subsystems interconnected with an external system in asymmetrical fashion. A sufficient condition for the quadratic stability of such a system is given interms of two modified subsystems with lower-order and corresponding H-norms,and it is shownthat the condition is also necessary for the quadratic stability of the overbounding system corresponding to the system.
