Abstract
In this paper, a class of competitive neural network models based on octonions is first constructed, and its predefined-time synchronization is explored by applying non-separation method and aperiodic complete intermittent control. Based on classification analysis and measurable selection theory, two novel equalities regarding octonion algebra are developed, which play a key role in studying the synchronization of octonion-valued systems using non-separation method and controllers with sign functions. Additionally, a new predefined-time stability lemma is proposed for systems with aperiodic complete intermittent controllers by utilizing mathematical induction. Then, two type of octonion-valued aperiodic complete intermittent controllers are designed for the first time to induce the predefined-time synchronization of the constructed model. Meanwhile, some new criteria for predefined-time synchronization are deduced. Finally, the effectiveness of the theoretical results is verified by a numerical example.
