This article is devoted to the synchronization of heterogeneous, and hence non-identical, linear systems. The proposed solution results in a fully distributed control law solely relying on local measurements. In order to achieve this, it is shown that the problem can be decomposed into three sub-problems: First, the synchronization of identical exosystems provides a feasible trajectory which turns out to be the synchronization manifold. Second, a decentralized observer is proposed for estimating the absolute state based on the local measurements performed. Third, this estimate is used to derive a tracking control law, based on the full information output regulation problem, to follow the generated exosystem reference. The concept is illustrated by an example.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
