Robust Output Regulation for a Class of Nonlinear Systems not Detectable by Regulated Output

摘要

This paper considers the robust output regulation problem for a class of nonlinear systems, not detectable by the regulated output. Differently from the previous results on the subject, it is supposed that the considered class of systems is in the normal form not defined on the conventional regulated output. We propose a novel internal model structure that, joined to a high-gain stabilizing action, solves the output regulation problem robustly with respect to possible uncertainties affecting the systems.
