Abstract
In this paper, the coordination control problem of discrete-time multi-agent systems (MASs) with uncertainties is studied by the output feedback technique, where the uncertainties are unknown disturbances and initial states. Firstly, a reduced-order neighborhood framer is constructed by using the boundary information of uncertainties. Secondly, a control protocol that depends on the absolute information of the agent framer is proposed by solving a modified algebraic Riccati equation. The results demonstrate that the control protocol can render a reduced-order neighborhood framer as a reduced-order neighborhood interval observer, which can not only realize the interval-valued estimation on the sum of the relative states between each agent and its neighbors in real time, but also realize the cooperative behavior of MASs under some sufficient conditions involving network synchronization and the instability degree of the agent. In addition, direct and indirect methods are proposed to eliminate the nonnegative constraint. Finally, the theoretical results are verified by two numerical simulations.
期刊介绍:
Automatica is a leading archival publication in the field of systems and control. The field encompasses today a broad set of areas and topics, and is thriving not only within itself but also in terms of its impact on other fields, such as communications, computers, biology, energy and economics. Since its inception in 1963, Automatica has kept abreast with the evolution of the field over the years, and has emerged as a leading publication driving the trends in the field.
After being founded in 1963, Automatica became a journal of the International Federation of Automatic Control (IFAC) in 1969. It features a characteristic blend of theoretical and applied papers of archival, lasting value, reporting cutting edge research results by authors across the globe. It features articles in distinct categories, including regular, brief and survey papers, technical communiqués, correspondence items, as well as reviews on published books of interest to the readership. It occasionally publishes special issues on emerging new topics or established mature topics of interest to a broad audience.
Automatica solicits original high-quality contributions in all the categories listed above, and in all areas of systems and control interpreted in a broad sense and evolving constantly. They may be submitted directly to a subject editor or to the Editor-in-Chief if not sure about the subject area. Editorial procedures in place assure careful, fair, and prompt handling of all submitted articles. Accepted papers appear in the journal in the shortest time feasible given production time constraints.
