区间二型T-S模型网络系统的安全控制设计

Security control design of interval type-2 T-S model-based networked systems

研究了具有参数不确定的区间二型模糊网络系统在遭受到拒绝服务攻击时的控制器设计问题。通过选取合适的Lyapunov-Krasovskii泛函,综合应用自由权矩阵、凸组合、Jensen不等式的方法并结合现有处理拒绝服务攻击的方式,设计了弹性事件触发策略下的安全控制器,并通过数例仿真验证设计方法的有效性。

The controller design problem of the interval-type 2 fuzzy network system with uncertain parameters when subjected to a denial of service attack is studied.By selecting appropriate Lyapunov-Krasovskii functional,comprehensively applying the methods of free weight matrix,convex combination,Jensen's inequality,and combining the existing methods of dealing with denial of service attacks,a security controller under flexible event trigger strategy was designed,and the validity of the design method is verified through several simulations.
