Abstract

The hybrid-triggered quantized H∞ control problem is investigated for discrete-time Markov jump systems (MJSs) under hybrid cyber attacks. A novel hybrid-triggered mechanism obeying Bernoulli distribution between the time-triggered mechanism and the adaptive event-triggered mechanism is introduced. The triggered condition considers the average value between current measured output and latest triggered output to avoid the unnecessary triggered data released. Meanwhile, a quantizer is adopted to optimize the data transmission rate and an observer-based controller is designed to resist the impact of deception attacks and aperiodic DoS attacks on the system. Utilizing Lyapunov stability theory and iterative methods, sufficient conditions are obtained to ensure that the closed-loop MJSs are asymptotically mean-square stable with H∞ performance. Then, an algorithm for gain matrices and triggered matrices is given. Finally, the effectiveness and availability of the proposed method are verified by a numerical example and a DC motor model.

具有量子化和混合攻击的马尔可夫跃迁系统的混合触发 H∞ 控制

研究了混合网络攻击下离散时间马尔可夫跃迁系统（MJS）的混合触发量化 H∞ 控制问题。引入了一种介于时间触发机制和自适应事件触发机制之间、服从伯努利分布的新型混合触发机制。触发条件考虑了当前测量输出与最新触发输出之间的平均值，以避免释放不必要的触发数据。同时，采用量化器优化数据传输速率，并设计了基于观测器的控制器，以抵御欺骗攻击和非周期性 DoS 攻击对系统的影响。利用李亚普诺夫稳定性理论和迭代法，得到了确保闭环 MJS 近似均方稳定且性能为 H∞ 的充分条件。然后，给出了增益矩阵和触发矩阵的算法。最后，通过一个数值实例和一个直流电机模型验证了所提方法的有效性和可用性。

期刊介绍： Systems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering refleSystems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering reflects this diversity by giving prominence to experimental application and industrial studies. "It is clear from the feedback we receive that the Journal is now recognised as one of the leaders in its field. We are particularly interested in highlighting experimental applications and industrial studies, but also new theoretical developments which are likely to provide the foundation for future applications. In 2009, we launched a new Series of "Forward Look" papers written by leading researchers and practitioners. These short articles are intended to be provocative and help to set the agenda for future developments. We continue to strive for fast decision times and minimum delays in the production processes."
