摘要: 针对一类受到混合网络攻击的离散时间非线性信息物理系统,研究了系统的事件触发自适应滑模控制问题.首先,为了降低网络通信负担,在量测信道中引入了自适应事件触发通信机制,同时考虑到系统受到的混合网络攻击模式特征,基于滑模动态和误差动态建立了增广闭环系统模型;其次,借助李雅普诺夫稳定性理论和线性不等式技术导出了闭环系统渐近稳定的充分条件,进而采用一种新型自适应滑模控制律,以补偿混合攻击对系统性能造成的负面影响,并确保系统状态被驱使到准滑模域中,保证了滑模域的可达性;最后,通过仿真算例验证了本文所提出控制方法的有效性与优越性.

Abstract: In this paper, the event-triggered adaptive sliding mode control problem is investigated for a class of discrete-time nonlinear cyber-physical systems under hybrid cyber attacks. Firstly, the adaptive event-triggered communication mechanism is introduced in the measurement channels to reduce the communication load. By considering the mode characteristics of hybrid cyber attacks, an augmented closed-loop system model is established based on sliding mode and error dynamics. Secondly, in terms of Lyapunov stability theory and linear inequality technique, sufficient conditions are derived to ensure the asymptotic stability of the augmented closed-loop system. Furthermore, a new adaptive sliding mode control law is proposed to compensate for the negative impact of hybrid cyber attacks on system performance, ensuring that the system state is driven into the quasi sliding mode domain and guaranteeing the accessibility of the sliding region. Finally, the effectiveness and superiority of the proposed control method are verified by a simulation example.
