Output feedback stabilization of Cyber-Physical System under DoS jamming attacks

Cyber-Physical Systems are easy to encounter the inherent and external factors in their network due to the shared communication method. In this paper, we study the output feedback stabilization of CPS with stochastic packet dropouts under DoS jamming attacks. Consider the DoS jammer has a limited energy budget and employs a periodic attack strategy to attack the measurement channel in the CPS. From the viewpoint of the CPS, we consider the case that the CPS does not know the DoS jammer's attack strategy, and an attack-tolerant mechanism is established. Sufficient condition of the controller existence is obtained by using stochastic Lyapunov function and linear matrix inequality approach. A numerical example is presented to demonstrate the effectiveness of the proposed control method finally.
