H∞ Control for Networked Control Systems with Packet Loss and Deception attack

In this paper, the robust H
∞
control problem is considered for a class of networked system with packet losses and deception attacks. There are random packet losses occur from sensor to controller and deception attacks occur from controller to actuator in this system. It is assumed that the random packet losses and deception network attacks both obey Bernoulli random binary distributions. Observer-based controller is designed because the state of the system cannot be fully observed. The closed-loop NCS is robustly stochastically exponentially stable and has achieved the prescribed H
∞
disturbance rejection attenuation property. Then, we conduct an analysis of the stability of the system exhaustively and address the controller synthesis problem. The controller design is effective when the LMI is shown to be solvable under certain conditions. Finally, the proposed LMI method has been proven to be effective through the use of a simulation example of uninterruptable power supply.
