This article investigates the switching-like event-triggered control for networked control systems (NCSs) under the malicious denial of service (DoS) attacks. First, by dividing the DoS attacks into S-interval (DoS-free case) and D-interval (DoS case), a switching-like event-triggered communication scheme (SETC) is well designed to deal with intermittent DoS attacks to improve communication efficiency while keeping the desired control performance. Second, by considering the SETC and NCSs into a unified framework, the studied system is transferred into a time-delay system. Then, under the constraint of the number of maximum allowable data dropouts induced by DoS attacks, a stability criterion and a stabilization criterion are derived, which can be used to estimate the event-triggered communication parameters and obtain the security controller gain simultaneously. Moreover, the derived stabilization criterion can also provide a tradeoff to balance communication efficiency and H∞ control performance. At last, a networked invert pendulum on a cart is conducted to show the effectiveness of the proposed method.

恶意拒绝服务攻击下网络控制系统的类开关事件触发控制


本文研究了恶意拒绝服务 (DoS) 攻击下网络控制系统 (NCS) 的类切换事件触发控制。首先，通过将DoS攻击分为S间隔（无DoS情况）和D间隔（DoS情况），设计了类切换事件触发通信方案（SETC）来应对间歇性DoS攻击，以改善通信效率，同时保持所需的控制性能。其次，通过将 SETC 和 NCS 考虑到一个统一的框架中，将所研究的系统转换为时滞系统。然后，在DoS攻击引起的最大允许数据丢失数的约束下，推导了稳定性判据和稳定性判据，可用于估计事件触发的通信参数并同时获得安全控制器增益。此外，导出的稳定准则还可以提供平衡通信效率和H∞控制性能的权衡。最后，在小车上进行网络化倒立摆实验，验证了该方法的有效性。
