It is assumed system is under cyber-attacks that occurred in sensor such that attacker can access to sensor and consequently injects false data to sensor. To achieve resilience in such conditions, at first a novel observer is proposed in order to estimate the actual states of system. Then a novel observer based controller is proposed in order to NCS in conditions of attack remains stable. Applying Lyapunov-Krasovskii functional method, delay dependent resilient criterion is established to show the exponential behavior of NCS in such conditions. Finally, for evaluating results, a practical example will be discussed.} }
