Secure Control for Networked Control Systems under Multiple Cyber-attacks

This paper focuses on the stability and controller design problem of networked control systems (NCSs) under multiple cyber-attacks, which are random and no priority has been pre-defined. A Markovian-based observer is designed to estimate the affected system states, with the desired gain changing with different attacks. Furthermore, a criterion is obtained in LMI to guarantee stochastically stable for closed-loop system and the corresponding controller design is addressed. Finally, the effectiveness of the proposed method is demonstrated by evaluating contrast simulation example.
