摘要
研究了马尔可夫跳变信息物理系统(CPS)在模态依赖拒绝服务(DoS)攻击下的安全控制问题.提出了一种模态依赖事件触发策略来减少网络资源消耗.特别地,DoS攻击被设置为依赖系统模态,从而更贴近实际的应用.基于Lyapunov Krasovskii泛函方法建立了闭环系统在DoS攻击下渐近一致有界的充分性条件.更进一步,根据矩阵技术设计了所需的安全控制器.最后,通过一个实例说明了该方法的有效性.
This study investigates the secure control problem of Markov jump cyber-physical systems(CPS)under mode-dependent denial of service(DoS)attacks.A novel mode-dependent event-triggering strategy is adopted to reduce the network resource consumptions.In particular,the DoS attacks are supposed to be mode-dependent for more practical applications.The Lyapunov-Krasovskii functional method is utilized to establish the sufficient conditions such that the resulting closed-loop system can be uniformly ultimately bounded under DoS attacks.Furthermore,the desired secure controller can be designed in terms of matrix techniques.Finally,an illustrative example is presented to demonstrate the effectiveness of the theoretical method.
