access icon free Robust output feedback hierarchical control for a class of non-linear systems

In this study, the authors address the problem of robust output feedback hierarchical control for a class of uncertain non-linear systems. The proposed approach is to design an output interface dynamic which is connected to the non-linear system and a linear abstract system. In order to deal with the uncertainties, they resort to the notion of internal model from output regulation. Finally, the unknown point mass system illustrates their approach.
