Abstract
The problem of prescribed-time output regulation for heterogeneous multi-agent systems (MASs) under DoS attacks is investigated in this letter. On the one hand, the system before and after the attack is established as a switching system, and the convergence of some or even all agents under DoS attacks is analyzed. On the other hand, a group of distributed prescribed-time observer-based state feedback controllers are designed to guarantee that the output regulation error converges to zero within prescribed-time, which can be specified by the user. Finally, a simulation example is used to verify the effectiveness of the main techniques in this letter.
本文研究了 DoS 攻击下异构多代理系统（MAS）的规定时间输出调节问题。一方面，将攻击前后的系统建立为一个切换系统，分析部分甚至全部代理在 DoS 攻击下的收敛性。另一方面，设计了一组基于规定时间观测器的分布式状态反馈控制器，以保证输出调节误差在用户指定的规定时间内收敛为零。最后，通过一个仿真实例验证了本文主要技术的有效性。
