Resilient Tracking Control of Networked Control Systems Under Cyber Attacks

This article is concerned with the resilient tracking control of a networked system under cyber attacks. The attacker an active adversary whose aim to severely degrade performance by launching deception attacks on sensor-to-controller communication channels and denial-of-service controller-to-plant channels, respectively. First, concept set-membership presented, through which system's true state guaranteed reside in bounding ellipsoidal set reference regardless existence unknown-but-bounded (UBB) noises. Second, case that full information not implicitly trusted presence attacks, estimation strategy provided secure estimates against Furthermore, based recursive computation ellipsoid confidence ellipsoids, convex optimization algorithm terms linear matrix inequalities proposed obtain gain parameters for both desired estimator controller. Finally, effectiveness method illustrated Internet-based three-tank system.
