The adaptive distributed observer for a leader system is a fully distributed dynamic
compensator for estimating the state variables and the system matrix of a linear leader
system over a communication network. In this paper, we first propose an event-triggered
implementation of the output-based adaptive distributed observer for a linear leader system
over jointly connected communication networks. Then we show that the proposed triggering
mechanism not only retains the exponential convergence property of the analog adaptive …

In this paper, the event-triggered output-based distributed observer (ETOBDO) is proposed
for a leader system with linear dynamics over switching communication networks satisfying
the jointly connected condition. Then ETOBDO is applied to solve the cooperative output
regulation problem (CORP) of linear heterogeneous multi-agent systems (MASs) over jointly
connected switching networks (JCSNs). Comparing with the similar results which only
implement the distributed observer by the event-triggering mechanism, we implement both …
