Abstract

In this article, the fixed-time resilient distributed Nash equilibrium (NE) control problem is addressed for nonlinear multiagent systems (MASs) under denial-of-service (DoS) attacks. Unlike existing results on NE seeking in noncooperative games, this article first investigates the layered fixed-time resilient distributed NE control problem for nonlinear MASs against DoS attacks, independent of initial conditions. To address these challenges, the novel layered NE control strategy is proposed, comprising a resilient fixed-time distributed NE seeking algorithm layer, an improved fixed-time performance enhancement layer, and an adaptive controller design layer. Specifically, a fixed-time resilient distributed NE seeking algorithm is first designed to guarantee players actions to converge toward the NE against DoS attacks. Then, novel high-order fixed-time filters are proposed to generate improved actions with smooth characteristics and converge to the actions in the aforementioned fixed-time algorithm. Based on the developed filters, a decentralized fuzzy adaptive controller is developed to achieve bounded tracking within the fixed time using the backstepping technique. Finally, a numerical simulation is conducted to validate the efficacy of the developed method.
针对DoS攻击的非线性质量固定时间弹性分布式网元寻优控制
本文研究了在拒绝服务(DoS)攻击下非线性多智能体系统的固定时间弹性分布式纳什均衡(NE)控制问题。与非合作博弈中网元搜索的现有结果不同,本文首先研究了非线性质量抵抗DoS攻击的分层固定时间弹性分布式网元控制问题,不依赖于初始条件。为了解决这些挑战,提出了一种新的分层网元控制策略,包括弹性固定时间分布式网元搜索算法层,改进的固定时间性能增强层和自适应控制器设计层。具体而言,首先设计了一种固定时间弹性分布式网元搜索算法,以保证玩家的动作收敛到网元上以抵御DoS攻击。然后,提出了一种新的高阶固定时间滤波器,以产生具有平滑特征的改进动作,并收敛于上述固定时间算法中的动作。在此基础上,设计了一种分散模糊自适应控制器,利用步进技术实现固定时间内的有界跟踪。最后,通过数值仿真验证了所提方法的有效性。
