AB  - The object of this article is to propose novel
observer-based resilient control for Networked Control
Systems (NCS) against cyber-attacks to sensor. 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.
