Game Control of Attack and Defense in Cyber Physical System

摘要

Cyber physical system (CPS) mainly relies on wireless network to realize information transmission from sensors to controllers and from the controllers to actuators. This paper studies the cyber-physical fusion system that is attacked by data packet timing. The attack and defense process is abstracted as a game process. Based on the two-person zero-sum game model of non-cooperative game, a variable delay situation is designed. In addition, this paper also compares the designed maximum-minimum controller with the linear quadratic Gaussian (LQG) control and carried out the simulation verification. It can be found that the controller designed in this paper can finally achieve stable control under attack.
