摘要

研究了异构多智能体系统(HMASs)在拒绝服务(DoS)攻击下的固定时间控制问题。提供了一种连续控制方案,使HMASs能够解决未知DoS攻击和任意初始条件下的固定时间遏制控制问题。为了减少控制器更新的频率,设计了一种基于事件触发条件的控制策略,解决了不需要连续更新控制器的定时控制问题。在系统初始状态被绑定的情况下,设计了一种改进的带有周期性事件触发条件的事件触发控制方案,避免了控制器的连续更新,并且不需要连续的系统消息。与已有的许多结果相比,所设计的控制方案在DoS攻击和初始条件未知的情况下都能解决固定时间的遏制问题。此外,给定的基于事件的控制方案可以避免芝诺行为。给出了数值算例来支持结果。

Fixed-time event-triggered and periodic event-triggered containment control for heterogeneous multi-agent systems under DoS attacks
This study explores the fixed-time containment control problem for heterogeneous multi-agent systems (HMASs) under denial-of-service (DoS) attacks. A continuous control scheme is provided to enable HMASs to solve fixed-time containment control problems with unknown DoS attacks and arbitrary initial conditions. To reduce the frequency of controller updates, a novel control strategy based on event-triggered conditions has been designed, which can settle the fixed-time containment control issue without requiring continuous controller updates. In the scenario where the initial states of the systems are bound, an improved event-triggered control scheme with periodic event-triggered conditions is designed, which can avoid continuous controller updates and does not need continuous system messages. Compared with many existing results, all the designed control schemes can settle fixed-time containment issues even when the DoS attacks and initial conditions are unknown. Moreover, the given event-based control schemes can avoid Zeno-behavior. Numerical examples are provided to support the results.

期刊介绍: Founded in 1981 by two of the pre-eminent control theorists, Roger Brockett and Jan Willems, Systems & Control Letters is one of the leading journals in the field of control theory. The aim of the journal is to allow dissemination of relatively concise but highly original contributions whose high initial quality enables a relatively rapid review process. All aspects of the fields of systems and control are covered, especially mathematically-oriented and theoretical papers that have a clear relevance to engineering, physical and biological sciences, and even economics. Application-oriented papers with sophisticated and rigorous mathematical elements are also welcome.
