As a continuation of our recent work (1999), this paper addresses the problem of decentralized robust output-feedback stabilization with disturbance attenuation for large-scale systems with strong nonlinear interconnections. We focuses on a constructive solution to this decentralized control problem without requiring common matching and growth conditions appearing in the past literature. The decentralized output-feedback laws proposed achieve internal global asymptotic stability in the sense of Lyapunov and external stability in the sense of Sontag (1995, 1998).
