本文研究了具有时变延迟的四元数值细胞神经网络(QVCNNs)的伪几乎周期同步问题。首先,利用Banach不动点定理,得到了具有时变时滞的qvcnn伪概周期解的存在性;然后,通过设计一种新颖的、非常通用的非线性状态反馈控制器,构造合适的Lyapunov函数,得到了伪概周期系数qvcnn的驱动响应结构可以实现全局指数同步。我们的结果是全新的。最后给出了一个数值算例,说明了所得结果的可行性。
In this paper, we consider the problem of the pseudo almost periodic synchronization of quaternion-valued cellular neural networks (QVCNNs) with time-varying delays. Firstly, we use the Banach fixed point theorem to obtain the existence of pseudo almost periodic solutions of QVCNNs with time varying delays. Then, by designing a novel and very general nonlinear state-feedback controller, and constructing suitable Lyapunov functions, we obtain that the drive-response structure of QVCNNs with pseudo almost periodic coefficients can realize the global exponential synchronization. Our results are completely new. Finally, a numerical example is given to illustrate the feasibility of our results.
