Topological Controllability of Undirected Networks of Diffusively-Coupled Agents
It addresses controllability analysis for multi-agent systems with signed edges, offering a new perspective beyond traditional structural controllability based on edge connectivity.
This paper establishes conditions for topological controllability in undirected networks of diffusively coupled agents based on edge signs (negative, positive, or zero), providing a merging process for constructing controllable graphs and a decomposition process for evaluating controllability.
This paper presents conditions for establishing topological controllability in undirected networks of diffusively coupled agents. Specifically, controllability is considered based on the signs of the edges (negative, positive or zero). Our approach differs from well-known structural controllability conditions for linear systems or consensus networks, where controllability conditions are based on edge connectivity (i.e., zero or nonzero edges). Our results first provide a process for merging controllable graphs into a larger controllable graph. Then, based on this process, we provide a graph decomposition process for evaluating the topological controllability of a given network.
