摘要: 针对具有混合网络攻击和介质访问约束的网络化控制系统,研究了系统的鲁棒安全控制问题.首先,考虑到混合网络攻击的模式特征和传感器访问约束的随机通信机制,将网络化系统建模为具有多个模态的马尔可夫跳变系统;其次,基于李雅普诺夫稳定性理论和线性矩阵不等式技术导出闭环系统随机稳定的充分条件,并设计了相应的H鲁棒安全控制策略,使得闭环系统随机稳定且具有给定的H性能;最后,通过仿真算例验证了所提控制方法的正确性和有效性.

Abstract: In this paper, the robust security control problem is investigated for networked control systems with hybrid cyber attacks and medium access constraints. Firstly, considering the pattern characteristics of hybrid cyber attacks and the stochastic communication mechanism of sensor access constraints, the networked systems are modeled as Markov jump systems with multiple modes. Secondly, sufficient conditions for the stochastic stability of the closed-loop systems are derived by utilizing Lyapunov stability theory and linear matrix inequality (LMI) techniques, and the robust security control strategy with the prescribed H performance is developed. Finally, an illustrative example is given to demonstrate the correctness and effectiveness of the proposed control method.

Key words: networked control systems, hybrid cyber attacks, medium access constraints, H robust control
