This paper considers the output consensus problem of high-order leader-following multiagent systems with unknown nonlinear dynamics, in which the delayed and sampled outputs of the system are the only available data. The unknown nonlinear dynamics are assumed to satisfy the Lipschitz condition and the interconnected topologies are assumed to be undirected and connected. A distributed observer-based output feedback controller is proposed for the system to reach output consensus. Both of the bounds of the allowable delay and sampling period are also obtained. Stability analysis shows that the considered systems are globally exponentially stable under the output feedback controller. Finally, a simulation example is given to validate our theoretical results.
Architectural decoration materials play an irreplaceable role in indoor design, landscape design and decoration design. A suitable decoration material can elevate the aesthetics and comfort of the overall space. There are numerous cases of ecological protection and aesthetic comfort achieved through rational use of architectural decoration materials in contemporary Chinese design; however, the indoor space design of rehabilitation center for autistic children is still out of step. This paper is to discuss the architectural decoration materials suitable for children’s rehabilitation from the perspective of particularity of autistic children, in order to provide a design blueprint for creating a safe and comfortable indoor space for autistic children, maximizing the treatment effect and improving their abnormal behaviors as well.
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.
