摘要

由于记忆混沌系统（MCS）固有的丰富动态特性，对其进行探索一直是一个突出的研究领域。本文旨在提出两个混沌系统，它们源自一个共同的基本系统，在保持多参数振幅调制和大规模偏移增强等共同属性的同时，还表现出共存吸引子和混沌鲁棒性等显著特点。通过分析分岔图、李亚普诺夫指数（LE）和相位投影，详细描述了 MCS 随参数和初始值变化的动力学行为演变过程。此外，数值模拟的结果通过电路实现得到了验证，从而进一步证实了所构建的两个记忆混沌系统的存在及其实际应用的潜力。

Simple memristive chaotic systems with complex dynamics

The exploration of memristive chaotic systems (MCSs) has been a prominent area of research due to the inherent richness of their dynamical characteristics. The objective of this paper is to propose two chaotic systems, derived from a common basic system, which also exhibit distinct characteristics such as coexisting attractors and robustness of chaos while maintaining the common attributes of multi-parameter amplitude modulation and large-scale offset boosting. The evolution process of MCSs' dynamical behavior with changes to parameters and initial values is described in detail through the analysis of bifurcation diagrams, Lyapunov exponents (LEs), and phase projections. Furthermore, the findings of the numerical simulations are validated by circuit implementations, thereby providing additional confirmation of the existence of the two memristive chaotic systems constructed and their potential for practical applications.

期刊介绍： Integration''s aim is to cover every aspect of the VLSI area, with an emphasis on cross-fertilization between various fields of science, and the design, verification, test and applications of integrated circuits and systems, as well as closely related topics in process and device technologies. Individual issues will feature peer-reviewed tutorials and articles as well as reviews of recent publications. The intended coverage of the journal can be assessed by examining the following (non-exclusive) list of topics: Specification methods and languages; Analog/Digital Integrated Circuits and Systems; VLSI architectures; Algorithms, methods and tools for modeling, simulation, synthesis and verification of integrated circuits and systems of any complexity; Embedded systems; High-level synthesis for VLSI systems; Logic synthesis and finite automata; Testing, design-for-test and test generation algorithms; Physical design; Formal verification; Algorithms implemented in VLSI systems; Systems engineering; Heterogeneous systems.
