This article studies the problems of exponential stabilization and ‐gain performance for networked control systems (NCSs) with transmission delays and periodic denial‐of‐service (DoS) attacks by exploring a resilient event‐triggered communication mechanism. First, a new resilient event‐triggered mechanism is developed to eliminate the adverse effects of network congestion caused by DoS attacks and decrease redundant communication so as to ensure efficient utilization of the limited network resources. The threshold parameter in the predefined event‐triggered condition can be adjusted according to the dynamic characteristics of the system. Then, an event‐driven control protocol is proposed, and a new switched NCS model is constructed. Sufficient conditions are then presented to ensure the exponential stability and ‐gain performance of the resulting closed‐loop system. Moreover, a co‐design scheme of the parameters in the event‐triggered condition and the controller gain is provided. Finally, the effectiveness and advantages of the new design techniques are verified through a comparative study for a robot manipulator control system.

拒绝服务攻击下网络控制系统的动态事件触发方法

本文通过探索弹性的事件触发通信机制，研究了具有传输延迟和周期性拒绝服务（DoS）攻击的网络控制系统（NCS）的指数稳定和增益性能问题。首先，开发了一种新的弹性事件触发机制，以消除由DoS攻击引起的网络拥塞的不利影响，并减少冗余通信，以确保有效利用有限的网络资源。可以根据系统的动态特性来调整预定义事件触发条件下的阈值参数。然后，提出了一个事件驱动的控制协议，并构造了一个新的交换式NCS模型。然后提供足够的条件以确保指数稳定性和产生的闭环系统的性能。此外，还提供了事件触发条件下的参数与控制器增益的协同设计方案。最后，通过对机器人机械手控制系统的比较研究，验证了新设计技术的有效性和优势。
