Global decentralised output regulation for a class of large-scale nonlinear systems with nonlinear exosystem

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