摘　　要：本文基于动态事件触发研究了受欺骗性攻击的非线性网络控制系统的故障检测问题。利用一个服从伯努利分布的随机变量来描述欺骗性攻击,设计了动态事件触发机制以节省网络资源,构造了相应的Lyapunov函数,得到了滤波误差系统均方渐近稳定且满足混合H∞和无源性能的充分条件。故障检测滤波器参数的设计以线性矩阵不等式的形式给出。最后通过一个数值算例,比较了动态事件触发方案与静态事件触发方案,说明了所提方法的有效性。This paper investigates the problem of fault detection in nonlinear networked control systems subject to deception attacks based on dynamic event-triggered mechanism. A random variable obeying the Bernoulli distribution is used to describe the deception attack. In order to save network resources, a dynamic event-triggered mechanism is designed, the corresponding Lyapunov function is constructed and sufficient conditions are obtained for the filtering error system to be mean-square asymptotically stable and to satisfy the mixed H∞ and passive property. The design parameters of the fault detection filter are given in the form of linear matrix inequalities. Finally, the effectiveness of the proposed method is illustrated by comparing the dynamic event-triggered scheme with the static event-triggered scheme through a numerical arithmetic example.
