Abstract

This paper is devoted to analyzing Fixed/Preassigned-time synchronization of T-S fuzzy complex networks (TSFCNs) with stochastic effects. Unlike the existing results, partial information communication and complete information communication are all considered according to a Bernoulli distribution. Furthermore, different controllers with quantization are structured to realize our synchronization goal, and one of control parameters can switch based on the error information. Besides, we derive sufficient conditions to guarantee Fixed-time(FDT) and Preassigned-time(PAT) synchronization of TSFCNs, and analyze the difference of FDT and PAT synchronization. Finally, numerical examples and comparisons show that our results are valid.

Keywords: Bernoulli distribution; Fixed/Preassigned-time synchronization; Partial information communication; Stochastic effects; T–S fuzzy complex networks.
