This article investigates the extended dissipative finite-time boundedness (ED-FTB) problem for fuzzy switched systems under deception attacks. To improve the network resource efficiency, a multidomain probabilistic event-triggered mechanism (MDPETM) is proposed. The mode mismatched phenomenon is modeled based on the switching delay information between the controller mode and the system mode. To extract the true signal generated by the MDPETM, a virtual delay concept is developed. The constraint that the controller and the system must have the same premise variables is removed. Based on the MDPETM, mismatched fuzzy state feedback controllers are first devised which may not share the same modes with the system. Then, by establishing fuzzy basis and controller mode-dependent Lyapunov functionals, sufficient criteria free of nonlinear terms existing in the literature are derived, which ensure the ED-FTB of the closed-loop system under admissible delays and deception attacks. Finally, an application-oriented one-link robotic arm system is utilized to validate the theoretical results.
本文研究了欺骗攻击下模糊切换系统的扩展耗散有限时间有界性(ED-FTB)问题。为提高网络资源效率,提出了一种多域概率事件触发机制(MDPETM)。基于控制器模式与系统模式之间的切换延迟信息对模式不匹配现象进行建模。为提取由MDPETM生成的真实信号,提出了虚拟延迟概念。去除了控制器与系统必须具有相同前提变量的约束。基于MDPETM,首先设计了可能与系统不共享相同模式的不匹配模糊状态反馈控制器。然后,通过建立模糊基和依赖于控制器模式的Lyapunov泛函,推导出了文献中不存在非线性项的充分准则,这些准则确保了闭环系统在允许延迟和欺骗攻击下的ED-FTB。最后,利用一个面向应用的单连杆机器人手臂系统对理论结果进行验证。
