Output regulation for decentralized networked control systems under jamming attacks and actuator saturation

摘要

Output regulation problem for a decentralized networked control system under jamming attacks and actuator saturation is solved by state feedback in this paper. A jammer's power allocation strategy aiming at degrading signal-interference-plus-noise ratios and leading to packets dropout in different wireless transmission channels of the decentralized networked control system is derived. In the presence of attack-induced packets dropout, a relation between null controllable region and regulatable region is described. For a plant and an exosystem, an asymptotically regulatable region is constructed based on a null controllable region. At last, an illustrative example certificates effectiveness of the presented techniques. (C) 2020 ISA. Published by Elsevier Ltd. All rights reserved.
