This paper addresses the non-fragile H-consensus control problem for multi-agent systems subject to deception attacks and missing measurements based on the designed observers. First of all, a sequence of Bernoulli distributed stochastic variables is applied to characterise the random nature of the missing measurements, where the changeable missing probability is constrained by a norm-bounded condition to reflect the reality more closely. Next, constraint conditions are given for the malicious signal considered in deception attacks with the purpose of limiting the difference between the attack signal and the true signal. The aim of this research is to design an observer-based non-fragile H-consensus controller for each agent such that the multi-agent closed-loop system can achieve the stochastic stability and meet the prescribed disturbance attenuation level when encountering the deception attacks and missing measurements. Then, based on Lyapunov stability theory, the sufficient condition is established to ensure the existence of the desired observer and controller. Moreover, the gain parameters are calculated by solving linear matrix inequalities. Finally, an explanative example is employed to demonstrate the effectiveness of the proposed distributed control algorithm.

欺骗攻击下基于观测者的多智能体系统非脆弱H∞共识控制

本文针对非脆弱性 H多代理系统的共识控制问题容易受到欺骗攻击并根据设计的观察者而缺少测量值。首先,应用一系列伯努利分布随机变量来表征缺失度量的随机性质,其中可变缺失概率受范数约束条件约束,以更紧密地反映现实。接下来,为限制欺骗攻击中考虑的恶意信号给出了约束条件,目的是限制攻击信号与真实信号之间的差异。这项研究的目的是设计一个基于观察者的非脆弱性H-每个智能体的共识控制器,以便多智能体闭环系统在遇到欺骗攻击和缺少测量值时,可以达到随机稳定性并达到规定的干扰衰减水平。然后,基于李雅普诺夫稳定性理论,建立了充分条件以确保所需观测器和控制器的存在。此外,通过求解线性矩阵不等式来计算增益参数。最后,一个说明性的例子被用来证明所提出的分布式控制算法的有效性。
