摘要:

研究了时变矩阵加权无向网络的一致性问题。首先,我们介绍了矩阵加权积分网络的分析,这样的网络。在对时变网络切换模式的适当假设下,给出了在相应积分网络的矩阵值Laplacian的零空间下,平均一致性可实现的充分必要条件.特别地,对于周期矩阵加权时变网络,从代数角度给出了达到平均一致性的充分必要条件。此外,我们表明,如果具有周期$T>0$的积分网络在时间跨度$[0,T)$上具有正的生成树,则实现了节点状态的平均一致性。仿真结果证明了理论分析的正确性。

英文摘要:

This paper examines the consensus problem on time-varying matrix-weighed undirected networks. First, we introduce the matrix-weighted integral network for the analysis of such networks. Under mild assumptions on the switching pattern of the time-varying network, necessary and/or sufficient conditions for which average consensus can be achieved are then provided in terms of the null space of matrix-valued Laplacian of the corresponding integral network. In particular, for periodic matrix-weighted time-varying networks, necessary and sufficient conditions for reaching average consensus is obtained from an algebraic perspective. Moreover, we show that if the integral network with period $T>0$ has a positive spanning tree over the time span $[0,T)$, average consensus for the node states is achieved. Simulation results are provided to demonstrate the theoretical analysis.
