摘　　要：研究了遭受拒绝服务(DoS)攻击的二维Roesser模型描述的系统镇定问题.通过DoS攻击的间歇性特征限制DoS频率和DoS持续时间,将原来的二维系统转化为一类切换系统;为了解决触发灵敏性较低而使系统动态性能下降和事件触发延长DoS攻击的持续时间的问题,提出了一种新的记忆型事件触发条件.此外,利用Lyapunov函数法,提出了一种状态反馈控制器的设计方法,并对闭环系统的指数稳定性进行了分析,利用线性矩阵不等式技术导出了控制器增益矩阵存在的充分条件;利用Darboux方程的仿真算例验证了所提出的事件触发控制方案的有效性.仿真结果表明,在所设计的控制方案下,闭环系统的状态是指数收敛的,能够弥补DoS攻击的恶意影响,减少通信资源的浪费.In this paper,the stabilization of two-dimensional systems described by the Roesser model under denial of service(DoS)attacks is studied.The original 2D system is rewritten into a class of switched systems by limiting the DoS frequency and DoS duration through the intermittent characteristics of DoS attacks.In order to solve the problem that the system dynamic performance is degraded due to low trigger sensitivity and the duration of DoS attacks is prolonged by event-triggered,a new memory-based event-triggered condition is proposed.In addition,a design method for state feedback controllers is proposed by using the Lyapunov function method,and the exponential stability of the closed-loop system is analyzed.Sufficient conditions for the existence of the controller gain matrix are derived by using linear matrix inequality techniques.The effectiveness of the proposed event-triggered control scheme is verified through the simulation of the Darboux equation.The simulation results show that under the designed control scheme,the state of the closed-loop system is exponentially convergent,compensating for the malicious impact of DoS attacks while also reducing the waste of communication resources.
