Abstract: This paper is concerned with the adaptive state observation and resilient control problem for a class of perturbed cyber-physical system against denial of service (DoS) attacks. An adaptive observer is firstly constructed to observe the compromised states under DoS attacks. Then based on the estimated sates, a resilient control strategy is developed to remedy the negative influence of DoS attacks and perturbations. By employing linear matrix inequality and Lyapunov stability theory, one can guarantee that the system states can track the desired signals of reference systems with time going to infinity. Furthermore, the state observation errors are guaranteed to remain a high accuracy. An aircraft system with different attack forms and attack modes is given to verify the effectiveness of designed adaptive observer and control methods.
