On Event-Triggered Implementation of Moving Target Defense Control

摘要

This paper proposes an event-triggered switched control system (ET-SCS) scheme for the implementation of moving target defense (MTD) control strategy in cyber-physical system (CPS). The proposed scheme uses the ET-SCS to obfustace the system structure/appearance while at the same time renders the closed loop CPS trajectories stable in the presence of cyber intrusion on the CPS actuator. The paper develops a mechanism for detecting the presence of such intrusions and then shows the asymptotic stability of the closed loop CPS.
