Research of Logarithmic Quantized Control of CPS with Actuator Attack
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.
