Abstract

This study introduces a novel theorem focusing on predefined-time stability within fractional-order systems and applies it to the domain of predefined-time synchronization in fractional-order memristive delayed bidirectional associative memory neural networks. Leveraging the inherent characteristics of fractional-order calculus and the fractional-order comparison principle, this theorem is showcased. Unlike existing predefined-time stability theorems that rely on integer-order counterparts, our theorem adopts the fractional-order framework. By utilizing this theorem as a foundation, efficient controllers are developed to achieve predefined-time synchronization. The theoretical outcomes are verified through the examination of two numerical examples, affirming the robustness and applicability of our approach.

分数阶记忆延迟BAM神经网络新的预定义时间稳定性定理及同步

本研究介绍了一个新定理，重点是分数阶系统中的预定义时间稳定性，并将其应用于分数阶忆苦思甜延迟双向联想记忆神经网络中的预定义时间同步领域。利用分数阶微积分的固有特征和分数阶比较原理，展示了这一定理。与依赖整数阶对应定理的现有预定义时间稳定性定理不同，我们的定理采用了分数阶框架。以该定理为基础，可以开发出高效的控制器来实现预定义时间同步。我们通过两个数值实例验证了理论成果，肯定了我们方法的稳健性和适用性。
