Large-scale systems occurring in several application domains (including, as a very short representative list, power systems, multi-agent systems, communication and transportation networks, supply chains, etc.) can be profitably viewed as interconnections of multiple subsystems. In this general context, the development of control algorithms for interconnected large-scale systems has attracted considerable research interest. Interest in decentralized control designs has been significantly renewed in recent years due to noteworthy extensions promised by the application of new results emerging in nonlinear robust and adaptive output-feedback control. In this vein, this chapter addresses the design of decentralized output-feedback controllers for a class of nonlinear interconnected large-scale systems based on our recent results on the dynamic high-gain scaling control design technique. The results here follow the general direction in the decentralized literature of attempting to generalize the form of the dynamics of subsystems and simultaneously weaken the assumptions on subsystem interconnections.
