摘要 为了研究记忆混沌系统的动力学特性,提出了一个含广义记忆元件的简单3维自治混沌系统。分析了混沌记忆系统的记忆效应和混沌特性,进行了电路设计和相应的实验验证;并在平衡点及稳定性分析的基础上,讨论了记忆混沌系统随参数变化的动力学行为。结果表明,与基于忆阻器的混沌电路不同,新提出的系统有一个确定的平衡点,其动力学行为仅依赖于系统控制参数,存在分岔、混沌和阵发混沌等复杂非线性现象。 To investigate the dynanrics of memory chaotic systems, a simple three-dimensional autonomous chaotic system containing a generalized memory element was proposed. The memory effects and chaotic characteristics of the memory chaotic system were analyzed, and circuit design and corresponding experimental verifications were performed. Based on the analysis of the equilibrium point and stabili- ty, the dynamical behaviors of the memory chaotic system with the variations of the parameter were discussed, The results indicated that, different from memristor based chaotic circuits, the new proposed system has unique equilibrium point, its dynamical behaviors only de- pend on the system control parameter and have complex nonlinear phenomena, such as bifurcation, chaos, and intermittencv chaos.
