Secure Control Against Multiplicative and Additive False Data Injection Attacks

In this paper, the secure control problem of the cyber-physical systems (CPS) is investigated when the communication network connecting a controller and an actuator is interfered by malicious adversaries. Both multiplicative and additive false data attacks are considered, and a general attack model is given to describe such attacks. Sufficient conditions are proposed to validate that whether a given controller is capable of maintaining the desired performance of CPS or not under a given attack scenario. Furthermore, conditions are given to design a secure controller for CPS with both multiplicative and additive false data attacks. Eventually, numerical simulation results are given to illustrate the effectiveness of the proposed secure control scheme in this paper.
