Cooperative global adaptive output regulation for nonlinear multi-agent systems with iISS inverse dynamics

In this paper, we present a further result on the cooperative global adaptive output regulation of nonlinear multi-agent systems with unity relative degree by relaxing the assumption on the inverse dynamics from input-to-state stable (ISS) to integral input-to-state stable (iISS). As the iISS condition is strictly weaker than the ISS condition, our result applies to a larger class of nonlinear multi-agent systems.
