Cooperative linear robust output regulation under uniformly connected switching network

The recent paper [9] studied the cooperative robust output regulation of linear multi-agent systems with arbitrary parametric uncertainty via the distributed output feedback control, where the network is assumed to be fixed. In this paper, we further show that the same controller is also efficient for the more general uniformly connected switching network. In contrast to the traditional quadratic Lyapunov function in literatures, the Lipchitz continuous Lyapunov function is developed here for the closed-loop system to guarantee its internal stability.
