Cooperative Global Robust Output Regulation for Nonlinear Multi Agent Systems in Output Feedback Form

Abstract

In this paper, we consider the global robust output regulation problem for a class of nonlinear multiagent systems by distributed output feedback control. We first show that the problem can be converted into the global stabilization problem of a class of multiinput, multioutput nonlinear systems called augmented system. Then, we further show that, under a set of standard assumptions, the augmented system can be globally stabilized by a distributed output feedback control law. Finally, we apply our approach to solve a leaderfollowing synchronization problem for a group of Lorenz multiagent systems.
