Abstract
In this paper, the fixed-time time-varying formation of heterogeneous multi-agent systems (MASs) based on tracking error observer under denial-of-service (DoS) attacks is investigated. Firstly, the dynamic pinning strategy is used to reconstruct the communication channel for the system that suffers from DoS attacks to prevent the discontinuous transmission information of the communication network from affecting MASs formation. Then, considering that the leader state is not available to each follower under DoS attacks, a fixed-time distributed observer without velocity information is constructed to estimate the tracking error between followers and the leader. Finally, adaptive radial basis function neural network (RBFNN) is used to approximate the unknown ensemble disturbances in the system, and the fixed-time time-varying formation scheme is designed with the constructed observer. The effectiveness of the proposed control algorithm is demonstrated by the numerical simulation.
本文研究了在拒绝服务(DoS)攻击下,基于跟踪误差观测器的异构多代理系统(MAS)的定时时变形成。首先,采用动态销钉策略为遭受 DoS 攻击的系统重建通信信道,防止通信网络传输信息不连续影响 MAS 的形成。然后,考虑到在 DoS 攻击下每个跟随者无法获得领导者的状态,构建了一个没有速度信息的固定时间分布式观测器来估计跟随者与领导者之间的跟踪误差。最后,使用自适应径向基函数神经网络(RBFNN)来近似系统中的未知集合干扰,并利用构建的观测器设计定时时变编队方案。数值仿真证明了所提控制算法的有效性。
