本文研究了在执行器故障和非周期拒绝服务(Denial of Service, DoS)攻击下不确定网络控制系统(Networked Control Systems, NCSs)基于事件触发机制的鲁棒有限时间稳定性。首先,基于离散事件触发通信方案,提出了一种类似切换的时滞系统模型。然后,通过构造分段Lyapunov-Krasovskii泛函,导出了保证系统有限时间稳定性的充分条件,并以线性矩阵不等式形式表示。此外,给出了鲁棒可靠控制器与事件触发参数的联合设计。最后,通过两个数值算例验证了提出方法的有效性。
In this paper, robust finite-time stability of Networked Control Systems (NCSs) based on event triggering mechanism under actuator failures and non-periodic Denial of Service (DoS) attacks is investigated. First, a switching-like delay system model is presented under discrete event-triggered communication scheme. Then, by constructing piecewise Lyapunov-Krasovskii functional, sufficient conditions for finite-time stability of the system are derived and expressed with a set of linear matrix inequalities. Moreover, the co-design of the robust reliable controller and the event-triggered parameter is obtained. Finally, two examples are employed to demonstrate the effectiveness of the proposed method.
