Abstract

In this article, a fractional Rocard's relaxation econometric oscillator is considered. Based on the fact that fractional derivatives incorporate memory factors, the integer order derivative is replaced by the Caputo fractional derivative. Stability and Hopf bifurcation conditions are obtained. Chaos in the fractional differential system is assessed by analyzing the Lyapunov characteristic exponents of the aforementioned system. Investigations show that the fractional system is chaotic and possesses similar dynamics, however, the bifurcation values differ from that of the classical system with a higher chaos occurrence probability.
分数阶混沌松弛计量振荡器的动力学分析
本文考虑了分数阶罗卡尔弛豫计量振子。基于分数阶导数包含内存因素的事实,整数阶导数被卡普托分数阶导数所取代。得到了稳定性条件和Hopf分岔条件。通过分析分数阶微分系统的李雅普诺夫特征指数来评价系统的混沌性。研究表明,分数阶系统是混沌的,具有相似的动力学特性,但其分岔值与混沌发生概率较高的经典系统不同。
