Abstract

This article investigates completely distributed secure consensus control (SCC) of high-order linear and Lipschitz nonlinear multiagent systems (MASs) in the presence of interaction link attacks, respectively, where the design criteria are independent of the interaction topology and the parameters of interaction link attacks. An estimator-based adaptive SCC protocol is proposed to realize SCC, where coupling weights of the virtual distributed reference state estimator (VDRSE) are adaptively adjusted to eliminate the impacts of interaction link attacks. Then, the leader–follower and leaderless structures are unified into a general directed graph framework by decomposing the Laplacian matrix in terms of the root node and nonroot node, and sufficient conditions for VDRSEs achieving reference state consensus and high-order linear MASs achieving SCC are given, respectively. Moreover, main results of high-order linear MASs are extended to Lipschitz nonlinear MASs. Finally, two numerical examples are presented in order to validate the theoretical results.

交互链接攻击下具有一般有向图的多代理系统的完全分布式安全共识

本文分别研究了存在交互链路攻击的高阶线性多代理系统（MAS）和利普希茨非线性多代理系统（MAS）的完全分布式安全共识控制（SCC），其中设计标准与交互拓扑和交互链路攻击参数无关。为实现 SCC，提出了一种基于估计器的自适应 SCC 协议，即自适应调整虚拟分布式参考状态估计器（VDRSE）的耦合权重，以消除交互链路攻击的影响。然后，通过分解根节点和非根节点的拉普拉卡矩阵，将领导者-跟随者结构和无领导者结构统一到一般有向图框架中，并分别给出了 VDRSE 实现参考状态共识和高阶线性 MAS 实现 SCC 的充分条件。此外，还将高阶线性 MAS 的主要结果扩展到 Lipschitz 非线性 MAS。最后，介绍了两个数值示例，以验证理论结果。

期刊介绍： This publication provides a systems-level, focused forum for application-oriented manuscripts that address complex systems and system-of-systems of national and global significance. It intends to encourage and facilitate cooperation and interaction among IEEE Societies with systems-level and systems engineering interest, and to attract non-IEEE contributors and readers from around the globe. Our IEEE Systems Council job is to address issues in new ways that are not solvable in the domains of the existing IEEE or other societies or global organizations. These problems do not fit within traditional hierarchical boundaries. For example, disaster response such as that triggered by Hurricane Katrina, tsunamis, or current volcanic eruptions is not solvable by pure engineering solutions. We need to think about changing and enlarging the paradigm to include systems issues.
