Decentralized Output Regulation for Large-scale Output-feedback Nonlinear Systems with Nonlinear Exosystem

This paper presents for the first time a solution to the problem of global decentralized output regulation for a class of large-scale uncertain nonlinear systems with nonlinear exosystem using error information. The proposed constructive approach does not require any matching conditions on the parametric uncertainties with some growth conditions on the interacting output nonlinearities. Two decentralized error feedback adaptive control strategies have been presented under some assumptions.
