摘要:如何有效利用和控制混沌系统在非线性科学研究中极为重要,是当今国际上热门且前沿的课题之一。分数阶混沌系统因其在动力学中的独特性质,使其在生物医学、神经网络等众多研究领域中都有巨大的价值,是目前的研究热点。本文基于李雅普诺夫稳定理论,利用预估校正法(Adams-
Bashforth-Moulton),提出了分数阶超混沌系统的函数级联同步方法。然后,我们以分数阶超混沌 系统、 系统、Lü系统为例,通过选择适当的控制子,实现了分数阶的函数级联同步,最后的数值模拟结果充分说明了我们所提出的同步方法是有效的。38830 毕业论文关键字:超混沌系统;混沌控制与同步;分数阶
Research on function cascade synchronization of fractional order hyperchaotic system
Abstract:How to use and control chaotic systems effectively is extremely important in nonlinear science research and becomes one of the most popular topics in the world. Due to the distinctive properties in dynamics, fractional chaotic systems have great values in many fields such as biomedicine and neural network, which make them be a hot topics nowdays. Based on the Lyapunov stability theory and use of the predictive correction method (Adams-Bashforth-Moulton), a function cascade synchronization algorithm for fractional hyperchaotic systems is proposed. Then, we take the fractional hyperchaotic Lorenz system, Chen system and Lü system as examples, by choosing suitable controllers, the fractional order cascade synchronization method is achieved. Finally, the numerical simulation results fully show the effectiveness of the synchronization method we proposed.
Key words:Hyperchaotic system; chaos control and synchronization; fractional order.
