Abstract

The study focuses on the secure synchronization control of a class of multi-weighted complex networks under denial-of-service attacks. First, a novel decentralized pinning observer is proposed to address the issue of unmeasurable node states. Furthermore, by employing iterative techniques, the comparison principle, and constructing appropriate Lyapunov functions, several security synchronization criteria expressed in terms of linear matrix inequalities are rigorously derived. Additionally, to minimize control costs, decentralized adaptive control strategies are developed to ensure secure synchronization. Finally, the feasibility and effectiveness of the theoretical analysis are validated through multiple numerical examples.

基于观察者的多权重复杂网络安全同步控制

研究了一类多权重复杂网络在拒绝服务攻击下的安全同步控制问题。首先，针对节点状态不可测的问题，提出了一种新的去中心化钉住观测器。此外，利用迭代技术、比较原理和构造适当的Lyapunov函数，严格推导了用线性矩阵不等式表示的几个安全同步准则。此外，为了使控制成本最小化，开发了分散自适应控制策略以确保安全同步。最后，通过多个数值算例验证了理论分析的可行性和有效性。
