Abstract

The existing results on the adaptive distributed observer for an uncertain leader system are restricted to connected static networks. In this article, we extend the existing results to acyclic every‐time connected switching networks. As an application of the adaptive distributed observer, we solve the leader‐following attitude consensus problem of multiple rigid body systems with an uncertain leader system over an acyclic every‐time connected switching network. A numerical example is provided to illustrate our design. [ABSTRACT FROM AUTHOR]

Abstract

The leader-following consensus problem for a class of multiple robot manipulators subject to a static and connected network has been studied recently by a distributed position feedback control law. In this technical note, we will further study the same problem under a switching network satisfying the jointly connected condition. Since the switching network can be disconnected at every time instant, the approach in the literature does not apply to the problem in this technical note. To deal with the disconnected switching network, we adopt the adaptive distributed observer approach to synthesize a distributed position feedback control law. It turns out that this control law solves the leader-following consensus problem for the class of multiple robot manipulators. The effectiveness of this new result is validated by an example.

Abstract

A standard assumption on the existence of the distributed observer or adaptive distributed observer for a linear leader system over jointly connected switching networks is that none of the eigenvalues of the system matrix of the leader system have positive real parts. In this paper, after establishing a stability result for a class of linear periodic switched systems, we present sufficient conditions for the existence of both the distributed observer and the adaptive distributed observer for general linear leader systems over periodic jointly connected switching networks. As an application of the distributed observer, we solve the cooperative output regulation problem for linear multi-agent systems with general linear leader systems over periodic jointly connected switching networks. A numerical example is provided to illustrate our design. [ABSTRACT FROM AUTHOR]
