Abstract This paper investigates the event-triggered H ∞ control of networked switched systems in the presence of Denial-of-Service (DoS) attacks. DoS attacks prevent the sampled information of system state and switching signal from transmitting among the network. The transmission delay on the switching of controller leads to asynchronous switching. By a suitable event-triggered scheme, the bound of the actual DoS-induced transmission delay is obtained, which can be used to construct a merged switching signal combining the switching signal of system with DoS-induced switching signal of controller. The original networked switched systems under DoS attacks can be modeled as new switched systems with this merged switching signal. By constructing multiple quadratic Lyapunov functions with the merged switching signal, some sufficient conditions are provided for event-triggered H ∞ controller. Finally, in order to demonstrate the effectiveness and feasibility of the proposed methods, a numerical simulation is performed.

受拒绝服务攻击的网络交换系统的事件触发 H∞ 控制

摘要 本文研究了在出现拒绝服务 (DoS) 攻击的情况下网络交换系统的事件触发 H ∞ 控制。DoS 攻击阻止系统状态采样信息和切换信号在网络之间传输。控制器切换时的传输延迟导致异步切换。通过合适的事件触发方案，得到了实际DoS引起的传输延迟的界限，该界可用于将系统的开关信号与控制器的DoS引起的开关信号相结合，构造一个合并的开关信号。DoS 攻击下的原始网络交换系统可以建模为具有此合并交换信号的新交换系统。通过用合并的开关信号构造多个二次李雅普诺夫函数，为事件触发的 H ∞ 控制器提供了一些充分条件。最后，为了证明所提出方法的有效性和可行性，进行了数值模拟。
