【摘要】 为了探究分数阶形式下该类系统的动力学特性,该文将分数阶微积分引入到忆阻退化Jerk系统中,增加了一个自由度,提升了系统性能。通过相图、分岔图、李雅普诺夫指数谱、复杂度混沌图等分析了系统的动力学特性,并采用DSP技术,实现了该系统的数字电路。研究结果表明,系统拓展到分数阶后有两种不同的单涡卷吸引子,系统随初值变化呈现倍周期分岔路径,在某些特定初值处系统演化路径出现跃变。系统具有无限多个吸引子共存。更多还原

【Abstract】 To investigate the dynamic characteristics of this type of system in the fractional-order case,fractional-order calculus is introduced into memristive hypogenetic Jerk system, which adds one degree of freedom and improves system performance. The dynamical characteristics of the system are analyzed by phase diagram, bifurcation diagram, Lyapunov exponent spectrum, complexity chaotic diagram, etc., and the digital circuit of the system is realized by employing DSP technology. The research results show that when the system is extended to the fractional order, the system presents a period doubling bifurcation path with the initial value, and the evolution path of the system changes abruptly at some specific initial values, showing infinite coexistence of attractors.更多还原
