研究了一类区间二型T-S模型网络控制系统在拒绝服务(Denial of Services,DoS)攻击下的类切换问题.首先,通过将DoS攻击划分为S-区间(无DoS情况)和D-区间(DoS情况),设计了类似开关的事件触发通信方案,用于处理间歇性DoS攻击,以提高通信效率和保持期望的控制性能.通常研究的H∞控制器,尝试设计一种在类切换事件触发下的L2-L∞控制器.最后,构建了适当的Lyapunov-Krasovskii泛函,通过一个数值模拟仿真结果验证了该设计方法的合理性.
L2-L∞ controller of interval Type-2 fuzzy networked control system under event triggered
The class switching problem of the network control system of the first-class interval type 2 T-S model under denial-of-service(DoS,Denial of Services)attack is studied.Firstly,by dividing the DoS attacks into S-interval(DoS-free case)and D-interval(DoS case),a switching-like event-triggered communication scheme is designed to deal with intermittent DoS attacks to improve communication efficiency while keeping the desired control performance.Controllers are usually studied H∞,trying to design a L2-L∞ controller that is triggered by a class of switching events.Finally,an appropriate Lyapunov-Krasovskii functional is constructed.The rationality of the design method is verified by a numerical simulation.
