摘要
分数微积分是分析非线性系统动力学的有效方法,能提供更精确的结果。在本研究中,首先介绍了 4 维 Pang 系统,并对其进行了动力学分析,展示了其超混沌结构。然后,介绍了该系统的分数阶计算,并研究了该系统在不同分数阶下的动力学特性。此时,根据 Lyapunov 指数和相空间表示法得出的结果,Pang 系统在不同分数阶表现出周期、混沌和超混沌行为。本研究最后得出的结果表明,在分数阶为 3.52 时,系统处于超混沌状态,同时也证实了所获得的结果比整数阶分析更为精确。研究的下一部分是分数阶系统的自适应同步。研究了三种不同的情况,结果表明所有情况下都能实现同步。
FRACTIONAL ORDER ANALYSIS OF THE 4-DIMENSIONAL HYPERCHAOTIC PANG SYSTEM AND ITS ADAPTIVE SYNCHRONIZATION
Fractional calculus is an effective method used to analyze the dynamics of nonlinear systems and provide more precise results. In this study, firstly, the 4-dimensional Pang system is introduced and its dynamic analyses demonstrating the hyperchaotic structure are given. Then, fractional-order calculations of the system are presented and the dynamics of the system for different fraction orders are investigated. At this point, according to the results obtained from Lyapunov exponents and phase-space representation, the Pang system exhibits periodic, chaotic, and hyperchaotic behaviors in different fractional orders. The results obtained at the end of this study present that the system is hyperchaotic for the fractional order of 3.52 and it is also confirmed that more accurate results are obtained than the integer-order analysis. In the next part of the study, adaptive synchronization of the fractional-order system is performed. Three different cases are examined and it is demonstrated that synchronization is achieved in all cases.
