In this article, the secure consensus problem is studied for a general linear multi-agent system, where a fully distributed event-triggered scheme is introduced to increase the feasibility and improve the scalability of the control protocol. Firstly, an edge-based sequential scaling attack is formulated with constraints on the attack duration and the frequency, which includes multiplicative deception attacks and DoS attacks as a particular situation when the scaling factor is equal to 0. Then a fully distributed event-triggered control protocol is designed, in which the global information is no longer needed. Sufficient conditions related to triggering parameters, the scaling factor, the attack duration and attack frequency are derived ensuring the asymptotic consensus of MAS. Furthermore, the impact of the triggering parameters and the scaling factor on the attack duration and the attack frequency are also discussed. The Zeno behavior is proved not to happen. Finally, two simulation examples based on unmanned intelligent vehicles are conducted to verify the results.
在本文中，研究了一般线性多智能体系统的安全一致性问题，引入了一种完全分布式事件触发方案，以提高控制协议的可行性并改善其可扩展性。首先，提出了一种基于边的顺序缩放攻击，对攻击持续时间和频率进行了约束，其中包括乘法欺骗攻击和当缩放因子等于0时作为特殊情况的拒绝服务攻击。然后设计了一种完全分布式事件触发控制协议，该协议不再需要全局信息。推导了与触发参数、缩放因子、攻击持续时间和攻击频率相关的充分条件，以确保多智能体系统的渐近一致性。此外，还讨论了触发参数和缩放因子对攻击持续时间和攻击频率的影响。证明了芝诺行为不会发生。最后，进行了两个基于无人智能车辆的仿真示例来验证结果。
