摘要

研究了具有未知有界外部干扰和测量噪声的线性离散网络物理系统的攻击检测问题。首先，设计了一种利用零阶保持器（ZOH）稳定控制信号的动态事件触发方案（DETS），以提高通信效率，同时保持系统性能。然后，在构造的DETS下，引入状态观测器的设计准则，保证观测器能够有效地估计系统状态并达到l1性能。在此基础上，提出了一种基于残差的攻击检测方法，提高了检测灵敏度，降低了虚警率。最后，通过数值算例验证了所提方法的有效性。

Zonotope-based attack detection for cyber-physical systems with a dynamic event-triggered scheme

In this paper, the attack detection problem of linear discrete-time cyber-physical systems (CPSs) with unknown-but-bounded (UBB) external disturbances and measurement noise is investigated. Firstly, a dynamic event triggering scheme (DETS) utilizing zero-order holds (ZOH) to stabilize control signals is designed to enhance communication efficiency while maintaining system performance. Then, under the constructed DETS, a design criterion for the state observer is introduced to guarantee that the observer can effectively estimate the system states and achieve

performance. Furthermore, a residual-based attack detection method is then proposed to enhance detection sensitivity and reduce the false alarm rate (FAR). Lastly, a numerical example serves to illustrate the effectiveness of the proposed approach.
