Abstract
ABSTRACTThis article considers the problem of output‐based dual dynamic periodic decentralized event‐triggered control (DPDETC) for nonlinear interconnected cyber‐physical systems (CPSs) subject to deception attacks. Taking into account the conflict between the limited network resources and the growing bandwidth demand, a dual dynamic periodic event‐triggered scheme (DPETS) is designed to reasonably decrease unnecessary data transmission, which includes sensor‐to‐controller (S‐C) and controller‐to‐actuator (C‐A) communication channels. For resisting the impact of attacks, a deception attacks model following Bernoulli distribution is introduced for nonlinear interconnected CPSs. Then, a new decentralized sampled‐data observer is proposed based on output‐dependent periodic event‐triggered conditions, such that the system output under deception attacks can be estimated. By means of decentralized observer and observer‐dependent DPETS, a new decentralized output feedback controller is established. The designed DPDETC strategy can guarantee that the nonlinear interconnected CPSs are mean square stability. Finally, simulation results are performed to validate the superiority of the designed DPDETC scheme.
