The problem of secure finite-horizon consensus control for discrete time-varying multiagent systems (MASs) with actuator saturation and cyber attacks is addressed in this article. A random attack model is first proposed to account for randomly occurring false data injection attacks and denial-of-service attacks, whose dynamics are governed by the random Markov process. The hybrid secure control scheme is developed to mitigate the influence of arbitrary cyber attacks on system performance. Specifically, this article proposes a hybrid control law containing multiple controllers, each of which is designed to counter different types of cyber attacks. By using the stochastic analysis approach, two sufficient criteria are provided to guarantee that the time-varying MASs satisfy the finite horizon H∞ consensus performance. Then, the controller parameters are obtained by solving the recursive linear matrix inequality. The usefulness of the theoretic results presented is demonstrated via a numerical example that contains a performance comparison of different secure control schemes.

针对网络攻击的多代理系统的安全有限视野共识控制。

本文讨论了具有执行器饱和和网络攻击的离散时变多智能体系统（MAS）的安全有限水平共识控制问题。首先提出一种随机攻击模型，以解决随机发生的错误数据注入攻击和拒绝服务攻击，其动态性由随机马尔可夫过程控制。开发混合安全控制方案是为了减轻任意网络攻击对系统性能的影响。具体来说，本文提出了一种混合控制法则，其中包含多个控制器，每个控制器旨在应对不同类型的网络攻击。通过使用随机分析方法，提供了两个充分的标准来保证时变的MAS满足有限水平H∞共识性能。然后，通过求解递归线性矩阵不等式获得控制器参数。通过一个包含不同安全控制方案的性能比较的数值示例证明了所提出的理论结果的有用性。
