Abstract

This article deals with the asynchronous event-triggered passive consensus issue for two-time-scale semi-Markov jump multiagent systems in continuous-time domain against denial-of-service (DoS) attacks. The multiagent systems are modeled with two-time-scale structures and the parameter changes are assumed to follow semi-Markov jump processes. For multiagent systems with two-time-scale structures, singular perturbed approaches are introduced to separate the coupled slow and fast dynamics of each agent. Then, double-rate sampling mechanisms are adopted for slow and fast dynamics with different evolution rates, and a novel asynchronous event-triggered scheme (AETS) with two independent triggering conditions is proposed. The asynchronous event-triggered scheme based on double-rate sampled-data reduces the transmission of unnecessary data and saves limited bandwidth resources by triggering independently on two time-scales. In addition, a consensus strategy is proposed to assure the multiagent system of achieving consensus with a specified passive performance level. Finally, the simulation example verifies that the asynchronous event-triggered scheme saves about 50% of network resources than the synchronous scheme under the premise of the same control effect.

DoS 攻击下具有双时间尺度特征的半马尔可夫跃迁多代理系统的异步事件触发被动共识

本文探讨了连续时间域中两时间尺度半马尔可夫跃迁多代理系统的异步事件触发被动共识问题，以对抗拒绝服务（DoS）攻击。多代理系统采用双时间尺度结构建模，并假定参数变化遵循半马尔可夫跃迁过程。对于具有双时间尺度结构的多代理系统，引入了奇异扰动方法来分离每个代理的慢速和快速耦合动态。然后，针对具有不同演化速率的慢动态和快动态采用了双速率采样机制，并提出了具有两个独立触发条件的新型异步事件触发方案（AETS）。基于双速率采样数据的异步事件触发方案通过在两个时间尺度上独立触发，减少了不必要的数据传输，节省了有限的带宽资源。此外，还提出了一种共识策略，以确保多代理系统以指定的被动性能水平达成共识。最后，仿真实例验证了在控制效果相同的前提下，异步事件触发方案比同步方案节省了约 50% 的网络资源。

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.
