L2 Control for Networked Control Systems Subject to Denial-of-Service Attacks

This paper focuses on the issue of designing L_2 state feedback controller for networked control systems subject to unknown periodic denial-of-service (DoS) jamming attacks. Primarily, a resilient event-triggering mechanism is introduced to counteract the influence of DoS jamming attacks. Secondly, a switching system model of NCSs is set up. Then, the criteria of the exponential stability analysis is obtained by the piecewise Lyapunov functional approach based on the model. Thirdly, a co-design approach of the trigger parameters and L_2 controller is developed. Lastly, a practical system is used for proving the efficiency of the proposed approach.
