Robust fixed-time synchronization of uncertain fractional-order quaternion-valued neural networks

Abstract

In this article, the robust fixed-time synchronization of uncertain fractional-order quaternion-valued neural networks(FQVNNs) is studied. By using direct analytical method and quaternion-valued inequality, a criterion for robust fixed-time synchronization is established, and the settling time for robust fixed-time synchronization is explicitly reckoned. Finally, the validity of the conclusions is illustrated via one numerical example.
