This paper is concerned with guaranteed cost control for a hybrid-triggered networked system subject to stochastic cyber-attacks. First, a hybrid-triggered mechanism including time-triggered mechanism and event-triggered mechanism is proposed to mitigate the pressure of network transmission, in which the switching between two mechanisms satisfies Bernoulli distribution. Second, the closed-loop system subject to the hybrid communication scheme and stochastic cyber-attacks is modelled as a stochastic system with an interval time-varying delay. Then, based on the Lyapunov-Krasovskii functional approach, two theorems are presented for guaranteeing the mean-square stability of the studied system. Finally, the effectiveness of the proposed method is demonstrated through a numerical example.
本文研究了受随机网络攻击的混合触发网络系统的保成本控制问题。首先，提出了一种包括时间触发机制和事件触发机制的混合触发机制，以减轻网络传输压力，其中两种机制之间的切换满足伯努利分布。其次，将受混合通信方案和随机网络攻击的闭环系统建模为具有区间时变延迟的随机系统。然后，基于Lyapunov-Krasovskii泛函方法，给出了两个定理以保证所研究系统的均方稳定性。最后，通过数值算例验证了所提方法的有效性。
