Cyber Physical Systems (CPS) such as power plants, water desalination utilities are just a few examples of systems that may come under stealth attacks. These attacks can threaten the proper operations of such systems without any indication. This problem necessitates the design of a control system that is able to work under such attacks. In this paper, an improved observer-based stabilising controller is proposed for CPS including random measurements and actuation delays and it is coming under distributed denial of service (DDoS) and deception attacks. The occurrences of DDoS and deception attacks are modelled as Bernoulli distributed white sequences with variable conditional probabilities. The criterion is presented in terms of linear matrix inequalities. Detailed simulation experiments on representative systems are shown to prove the applicability of the proposed methodology.

安全控制受随机分布式 DoS 和欺骗攻击的网络物理系统

发电厂、海水淡化设施等网络物理系统 (CPS) 只是可能受到隐形攻击的系统的几个例子。这些攻击可能会在没有任何迹象的情况下威胁此类系统的正常运行。这个问题需要设计一个能够在此类攻击下工作的控制系统。在本文中，针对 CPS 提出了一种改进的基于观察者的稳定控制器，包括随机测量和驱动延迟，并且它正在遭受分布式拒绝服务 (DDoS) 和欺骗攻击。DDoS 和欺骗攻击的发生被建模为具有可变条件概率的伯努利分布的白色序列。该标准以线性矩阵不等式表示。
