摘　　要：针对拒绝服务(DoS)攻击下的二维F-M系统,基于事件触发机制设计了一种满足H∞性能的弹性滤波器。首先,对二维DoS攻击和事件触发机制进行建模,设计了一个弹性滤波器,构造了增广滤波误差系统并给出了预设的性能指标。其次,基于随机分析方法和Lyapunov理论,给出了确保二维增广滤波误差系统鲁棒稳定的充分判据,推广得出增广滤波误差系统具有鲁棒H∞性能。再次,通过求解相关矩阵不等式,给出了弹性滤波器参数的显式表达式。最后,通过仿真实例验证了理论结果的可行性。In this paper,a resilient filter with H∞performance is designed based on an event-triggered scheme for two-dimensional(2-D)F-M system under denial of service(DoS)attacks.Firstly,a 2-D DoS attack and an event-triggered scheme are modeled,and then a resilient filter is designed.An augmented filtering error system is constructed and preset performance index is provided.Secondly,based on random analysis method and Lyapunov theory,sufficient criteria are provided to ensure the robust stability of the 2-D augmented filtering error system.Further deriving from the results,it is found that the augmented filtering error system has robust H∞performance.Thirdly,an explicit expression for the parameters of the resilient filter is given by solving the relevant matrix inequality.Finally,the feasibility of the theoretical results is verified through simulation examples.
