Finite-Time Nonfragile Synchronization Control of Time-Varying Delays T-S Fuzzy Discrete Chaotic Network Systems With Deception Attacks

Abstract

This article addresses the finite-time nonfragile synchronization control of time-varying delays T-S fuzzy discrete chaotic network systems(TSFDCNSs) with random deception attacks. Aiming at the security threats caused by network attacks in network system, a nonfragile feedback controller is designed considering random deception attacks. In order to reduce communication resource consumption effectively, an adaptive event triggering method is proposed based on adaptive threshold parameters. Under the Lyapunov-Krasovskii functional and linear matrix inequality, we derive sufficient conditions for the finite-time synchronization of TSFDCNSs. Finally, two examples are given to validate the proposed modes.
