Hidden Dynamic Analysis of a New Nonlinear System
摘要/Abstract
忆阻器是一种新的电路元件，为非线性电路的设计提供了全新的发展空间.以忆阻电路为基础，建立了一个新的四维动态系统. 为了获得更丰富的动力学行为，在该系统中引入了2个可调参数，从而形成了一个具有各种隐藏吸引子的统一非线性系统. 通过改变可调参数，找到4种不同类型的隐藏吸引子和自激吸引子. 通过MATLB数值仿真，利用相图和Lyapunov指数谱等工具，研究了四维混沌系统的动力学行为及其隐藏振荡行为. 新的统一混沌系统有助于研究隐藏吸引子的特性、动态系统中动力学行为的复杂性.
Memristor is a new circuit element, which provides a new development for the design of nonlinear circuits. Based on memristor circuit, a new 4-D dynamic system is established. In order to obtain more abundant dynamic behaviors, two parameters are introduced into the system to form a unified chaotic system with various hidden attractors. By changing the parameters, four different types of hidden attractors and self-excited attractor can be found. This unified chaotic system is helpful for us to understand the characteristics of hidden attractors and study the complexity of dynamic behaviors in dynamic systems.
