Robust adaptive estimation and tracking control for perturbed cyber-physical systems against denial of service

作者:

Highlights:

• An adaptive estimation scheme is proposed to observe the compromised states under DoS attacks by using normal coupled signals.

• The designed time-varying observer gain is also applicable to the presence of perturbation.

• A resilient control strategy is developed to achieve the bounded tracking result of system under DoS attacks and perturbations.

• The proposed state observation and resilient control methods can guarantee the high accuracy of the state estimation error and tracking error under DoS attacks.
