一类非平稳一致算法收敛性的紧估计

Tight estimates for convergence of some non-stationary consensus algorithms

David Angeli, Pierre-Alexandre Bliman

摘要:

本文主要研究一类离散多智能体系统的一致收敛速度估计问题。在这里考虑的系统中,互连图的拓扑结构和弧的权重都允许作为时间的函数而变化。在一定的生成树结构是保持沿时间的假设下,一些非零的最小重量的信息传递沿这棵树是保证,收缩率的估计。后者被明确表示为依赖于树深度和权值的下界的某个矩阵的谱半径。

英文摘要:

The present paper is devoted to estimating the speed of convergence towards consensus for a general class of discrete-time multi-agent systems. In the systems considered here, both the topology of the interconnection graph and the weight of the arcs are allowed to vary as a function of time. Under the hypothesis that some spanning tree structure is preserved along time, and that some nonzero minimal weight of the information transfer along this tree is guaranteed, an estimate of the contraction rate is given. The latter is expressed explicitly as the spectral radius of some matrix depending upon the tree depth and the lower bounds on the weights.
