摘要
针对遭受执行器攻击且被对数量化器量化的信息物理融合系统,研究了系统的稳定性以及控制器的设计问题.利用对数量化器的扇形界性质将遭受攻击的量化系统转化为一个不确定系统,首先,通过构造一个李雅普诺夫函数给出了此系统稳定的充分条件.其次,利用Schur-补引理将系统稳定的充分条件转化为一组线性矩阵不等式,并在此基础上给出了系统控制器的设计方法.最后,用数值例子验证了所提出的方法的有效性,仿真结果表明,上述方法可以使系统达到稳定.
Abstract
In this paper,we mainly focus on the logarithmic quantized control of cyber-physical systems with ac-tuator attacks.The stability of the system and the design of the controller are analyzed in detail.The sector-bound property of the logarithmic quantizer is used to convert the attacked quantization system into an uncertain system.Firstly,the sufficient condition to stabilize the system is given by constructing a Lyapunov function.Secondly,using Schur Compliment Lemma,the sufficient condition is converted into some LMIs.The design method of the system con-troller is given based on these LMIs.Finally,a numerical example is given to illustrate the results obtained in this pa-per.The simulation results show that this method can make the system stable.
