This article considers the security-based passivity problem for a class of discrete-time Markov jump systems in the presence of deception attacks, where the deception attacks aim to change the transmitted signal. Considering the impact of deception attacks on network disruption, it causes the existence of time-varying delays in signal transmission inevitably, which makes the controlled system and the controller work asynchronously. The asynchronous control method is employed to overcome the nonsynchronous phenomenon between the system mode and controller mode. On the other hand, to reduce the frequency of data transmission, a resilient asynchronous event-triggered control scheme taking deception attacks into account is designed to save communication resources, and the proposed controller can cover some existing ones as special examples. Moreover, different triggering conditions corresponding to different jumping modes are developed to decide whether state signals should be transferred. A new stability criterion is derived to ensure the passivity of the resultant system although there exist deception attacks. Finally, a simulation example is given to verify the theoretical analysis.
本文研究了一类存在欺骗攻击的离散时间马尔可夫跳跃系统基于安全性的无源性问题,其中欺骗攻击旨在改变传输信号。考虑到欺骗攻击对网络中断的影响,不可避免地导致信号传输中存在时变延迟,这使得受控系统和控制器异步工作。采用异步控制方法来克服系统模式和控制器模式之间的不同步现象。另一方面,为了降低数据传输频率,设计了一种考虑欺骗攻击的弹性异步事件触发控制方案以节省通信资源,并且所提出的控制器可以涵盖一些现有控制器作为特殊示例。此外,针对不同的跳跃模式开发了不同的触发条件来决定是否应传输状态信号。推导了一个新的稳定性准则以确保在存在欺骗攻击的情况下所得系统的无源性。最后,给出了一个仿真例子来验证理论分析。
