Output-Based Distributed Observer for General Linear Leader Systems Over Periodic Switching Digraphs and Its Application *

In this paper, we first establish an output-based distributed observer for a general linear leader system over a periodic jointly connected switching communication network, which extends the applicability of the output-based distributed observer from a marginally stable linear leader system to any linear leader system and from an undirected switching graph to a directed switching graph. Then we further solve the cooperative output regulation problem of linear multi-agent systems utilizing the output-based distributed observer.
