This article mainly dedicates on the issue of finite-time stabilization of complex-valued neural networks with proportional delays and inertial terms via directly constructing Lyapunov functions without separating the original complex-valued neural networks into two real-valued subsystems equivalently. First of all, in order to facilitate the analysis of the second-order derivative caused by the inertial term, two intermediate variables are introduced to transfer complex-valued inertial neural networks (CVINNs) into the first-order differential equation form. Then, under the finite-time stability theory, some new criteria with less conservativeness are established to ensure the finite-time stabilizability of CVINNs by a newly designed complex-valued feedback controller. In addition, for reducing expenses of the control, an adaptive control strategy is also proposed to achieve the finite-time stabilization of CVINNs. At last, numerical examples are given to demonstrate the validity of the derived results.
本文主要致力于具有比例时滞和惯性项的复值神经网络的有限时间稳定性问题,通过直接构建李雅普诺夫函数,而无需将原始复值神经网络等效地分为两个实值子系统。首先,为了便于分析惯性项引起的二阶导数,引入两个中间变量将复值惯性神经网络(CVINN)转化为一阶微分方程形式。然后,在有限时间稳定性理论的基础上,通过设计新的复值反馈控制器,建立了一些具有更小保守性的新准则,以确保 CVINN 的有限时间稳定性。此外,为了降低控制成本,还提出了一种自适应控制策略,以实现 CVINN 的有限时间稳定性。最后,通过数值实例验证了所得结果的有效性。
