Finite time synchronization, which means synchronization can be achieved in a settling time, is desirable in some practical applications. However, most of the published results on finite time synchronization don't include delays or only include discrete delays. In view of the fact that distributed delays inevitably exist in neural networks, this paper aims to investigate the finite time synchronization of memristor-based Cohen-Grossberg neural networks (MCGNNs) with both discrete delay and distributed delay (mixed delays). By means of a simple feedback controller and novel finite time synchronization analysis methods, several new criteria are derived to ensure the finite time synchronization of MCGNNs with mixed delays. The obtained criteria are very concise and easy to verify. Numerical simulations are presented to demonstrate the effectiveness of our theoretical results.
有限时间同步意味着可以在一个稳定时间内实现同步,这在一些实际应用中是很理想的。然而,大多数已发表的关于有限时间同步的结果都不包括延迟或仅包括离散延迟。鉴于神经网络中不可避免地存在分布延迟,本文旨在研究具有离散延迟和分布延迟(混合延迟)的基于忆阻器的Cohen-Grossberg神经网络(MCGNNs)的有限时间同步。通过一个简单的反馈控制器和新颖的有限时间同步分析方法,推导出了几个新的准则,以确保具有混合延迟的MCGNNs的有限时间同步。所得到 的准则非常简洁且易于验证。给出了数值模拟以证明我们理论结果的有效性。
