Abstract

This paper focuses on the consensus problem for second-order multi-agent systems with impulsive algorithm and communication time-delays. By introducing a state transformation, the consensus of the system is translated into the asymptotical stability of a reduced-order discrete-time system. Based on the properties of Laplacian matrix of graphs and a given invertible matrix, necessary and sufficient conditions are established for the consensus convergence in the cases of directed and undirected topologies. Two numerical simulations are worked out to illustrate the effectiveness of the theoretical results.

Abstract

This paper focuses on studying the group consensus tracking issue of continuous-time second-order multi-agent systems (MASs) under directed fixed topology. A new protocol is introduced under the assumption that all the subgroups satisfy the in-degree balanced condition. For MASs with two subgroups, we first establish the relationship between the positive stability of matrix H and the connectedness of the topology graph. Then, we prove that MASs can achieve group consensus tracking if the system parameters satisfy some inequalities and matrix H is positive stable. Moreover, our paper extends the results for MASs with two subgroups to multiple χ -group consensus tracking. Especially, for a special graph with acyclic partition, a necessary and sufficient condition of χ -group consensus tracking is established. Finally, simulation examples are given to illustrate the effectiveness of our results. [ABSTRACT FROM AUTHOR]

Abstract

Controllability is a fundamental issue concerning control of multi-agent networks and a very important research topic in the modeling, analysis and coordination control of multi-agent systems. Group controllability problem is a further extension of the controllability problem of the general multi-agent systems, which mainly studies the cooperation and control of multi-agent systems with multiple sub-groups or multiple intelligence clusters. Comparing with the controllability of the general multi-agent systems, the group controllability is not only to consider the information interaction among the groups, but also to consider the information interaction between different groups, which makes the system reflect the effect of a whole and also the internal structure of the sub-groups. This paper addresses the group controllability problems of discrete-time multi-agent systems with time-delay, in which both switching topology and fixed topology are considered. This paper also proposes the general definition of the group controllability, as well as establishes group controllability criteria from the algebraic and graphical perspectives. Numerical examples and simulations are proposed to illustrate the theoretical results. [ABSTRACT FROM AUTHOR]
