摘要

研究了一类具有泄漏和离散延迟的扩散Hopfield神经网络的有限/固定时间同步问题。为了保证寻址网络模型在统一框架下的FFTS性能，建立了一些新的、有用的、不依赖于时滞而依赖于扩散系数的准则。与既有扩散效应又有泄漏延迟的系统只能有限及时或固定及时同步的结果形成鲜明对比，本文的理论结果更具通用性和实用性。最后，通过数值算例验证了所提控制方法的有效性。

Finite-/fixed-time synchronization of leakage and discrete delayed Hopfield neural networks with diffusion effects

In this paper, the problem on finite-/fixed-time synchronization (FFTS) is investigated for a class of diffusive Hopfield neural networks with leakage and discrete delays. Some new and useful criteria independent on time delays but dependent on the diffusion coefficients are established to guarantee the FFTS for the addressed network model under a unified framework. In sharp contrast to the existed results which can only finite-timely or fixed-timely synchronize the systems with both diffusion effects and leakage delays, the theoretical results of this paper are more general and practical. Finally, a numerical example is presented to show the effectiveness of the proposed control methods.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
