Global output regulation for output feedback systems with an uncertain exosystem and its application

INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL, Issue 15 2010
Dabo Xu
Abstract This paper presents the solvability conditions for the global robust output regulation problem for a class of output feedback systems with an uncertain exosystem by using output feedback control. An adaptive control technique is used to handle the unknown parameter vector in the exosystem. It is shown that this unknown parameter vector can be exactly estimated asymptotically if a controller containing a minimal internal model is employed. The effectiveness of our approach has been illustrated by an asymptotic tracking problem of a generalized fourth-order Lorenz system. Copyright © 2009 John Wiley & Sons, Ltd. [source]

Robust output regulation for discrete-time nonlinear systems

INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL, Issue 2 2005
Weiyao Lan
Abstract In this paper, we will establish a framework that can convert the robust output regulation problem for discrete-time nonlinear systems into a robust stabilization problem for an appropriately augmented system consisting of the given plant and a specific dynamic system called internal model. We then apply this framework to solve the local robust output regulation problem for a general class of discrete-time nonlinear systems. The results of this paper gives a discrete-time counterpart of the recent results on the continuous-time robust output regulation problem. Copyright © 2005 John Wiley & Sons, Ltd. [source]

On a robust synchronization problem via internal model approach,

ASIAN JOURNAL OF CONTROL, Issue 1 2010
Weijie Sun
Abstract This paper formulates the synchronization of the Duffing system and the Van der Pol oscillator as a robust output regulation problem and presents the solution to this problem based on the internal model design. The controller thus obtained is able to achieve the synchronization of the outputs of these two systems in the presence of the parameter uncertainty of the Duffing system.
