摘要

提出了一种具有参数控制的球形多涡旋记忆保守超混沌系统，并通过平衡点、散度、Lyapunov指数和Kaplan-Yorke维数的分析验证了系统的保守性和混沌性。研究发现，在两种不同的系统参数下，球卷数呈现出两种不同的变化形式，且系统具有大范围的超混沌特性。然后，研究了状态变量控制下的偏移增强、初值控制下的偏移增强以及系统的多稳定性，得到了三种不同类型的共存吸引子。同时，随着时间的推移，系统会出现两种暂态转变行为。最后，利用FPGA实现了系统的硬件实现。

Analysis and implementation of a novel parametrically controllable spherical multi-scroll memristive conservative hyperchaotic system

A spherical multi-scroll memristive conservative hyperchaotic system with parameter control is proposed, and the system's conservatism and chaos are verified by analysis of equilibrium point, divergence, Lyapunov exponent, and Kaplan-Yorke dimension. We found that the number of spherical scrolls shows two different forms of variation with two different system parameters, and that the system has a large range of hyperchaotic characteristics. Then, offset-boosting under state variables control, offset-boosting under initial value control and multistability of the system are investigated, and three different types of coexisting attractors are found. Meanwhile, two kinds of transient transition behaviours occur in the system with time. Finally, the system's hardware is implemented using FPGA.

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.
