      针对具有多信道随机欺骗攻击的Markov跳变系统, 首次提出一种新颖的基于动态事件触发机制(DETM)和量化的异步输出反馈控制器. 为了减少网络中的通信负担, 采用DETM和量化相结合的控制方法. 为了提高信道的非脆弱性, 设计基于隐马尔可夫模型(HMM)的多信道传输策略. 同时, 考虑由伯努利变量描述的随机多信道欺骗攻击. 为了刻画系统与控制器之间模态不匹配现象, 设计基于HMM的异步控制律. 通过构造模态依赖的Lyapunov函数, 建立闭环系统随机稳定和严格耗散充分条件. 最后, 通过应用质量–弹簧–阻尼器机械系统实例验证所提出设计方法的有效性和实用性.

英文摘要

      In this article, a novel asynchronous output feedback controller based on the dynamic event-triggered mechanism and quantization is proposed for Markov jump systems with random deception attacks in the multi-channel transmission firstly. In order to reduce the communication burden in the shared network, the dynamic event-triggered mechanism and quantized strategy are attained. To improve the non-fragile of the transmission channel, the multi-channel data transmission strategy based on the hidden Markov model (HMM) method is adopted. In the meanwhile, stochastically occurring multi-channel deception attacks described by Bernoulli variables are considered. The asynchronous control law is designed using HMM, which characterizes the mismatch between the system mode and the controller mode. By constructing the mode-dependent Lyapunov function, sufficient conditions to ensure the stochastic stability and strict dissipative of the closed-loop system are established. Finally, an example of the mass-spring-damper mechanical system is presented to verify the effectiveness and practicability of the proposed method.
