This paper studies the output-based security control of networked control systems under resilient event-triggered mechanism (RETM) and periodic denial-of-service (DoS) attacks. Firstly, using attack period and sleeping interval of jammer, an output-based resilient event-triggered mechanism is introduced, which can save system resources despite DoS attacks. Secondly, a switched system model is built, which integrates impacts of the RETM and DoS attacks in a unified framework. Thirdly, using piecewise Lyapunov functional approach, exponential stability criteria are obtained, which establish quantitative relationships among the RETM, DoS attacks, sampling period and exponential decay rate. Further, sufficient conditions for co-designing the RETM and output-based security controller are presented. Finally, example confirms effectiveness of the proposed method.

弹性事件触发机制和 DoS 攻击下基于输出的 NCS 安全控制

本文研究了在弹性事件触发机制 (RETM) 和周期性拒绝服务 (DoS) 攻击下的网络控制系统的基于输出的安全控制。首先，利用干扰器的攻击周期和休眠间隔，引入基于输出的弹性事件触发机制，在DoS攻击的情况下也能节省系统资源。其次，构建了一个交换系统模型，将 RETM 和 DoS 攻击的影响集成在一个统一的框架中。第三，使用分段Lyapunov函数方法，获得指数稳定性准则，建立了RETM、DoS攻击、采样周期和指数衰减率之间的定量关系。此外，还提出了共同设计 RETM 和基于输出的安全控制器的充分条件。最后，
