研究了Rossler系统的动力学行为,用Lyapunov指数理论论证了该系统存在混沌现象,数值仿真的相图揭示了混沌现象存在的具体形式,全局分岔图显示了随着系统参数的变化,系统由周期轨道经倍化分岔序列通向混沌的动力学特性。系统随不同参数变化的分岔图表明:随着参数的变化,系统变化的趋势基本一致,只是系统参数变化的方向不同,系统变量的取值范围不同。利用比例微分控制器控制混沌,当控制参数取恰当数值时,该方法能将系统控制到期望的周期轨道。该文进一步完善了对Rossler系统动力学行为的研究,为该系统混沌行为的抑制及实际工程的应用提供了理论依据。
研究瞭Rossler繫統的動力學行為,用Lyapunov指數理論論證瞭該繫統存在混沌現象,數值倣真的相圖揭示瞭混沌現象存在的具體形式,全跼分岔圖顯示瞭隨著繫統參數的變化,繫統由週期軌道經倍化分岔序列通嚮混沌的動力學特性。繫統隨不同參數變化的分岔圖錶明:隨著參數的變化,繫統變化的趨勢基本一緻,隻是繫統參數變化的方嚮不同,繫統變量的取值範圍不同。利用比例微分控製器控製混沌,噹控製參數取恰噹數值時,該方法能將繫統控製到期望的週期軌道。該文進一步完善瞭對Rossler繫統動力學行為的研究,為該繫統混沌行為的抑製及實際工程的應用提供瞭理論依據。

This paper studied the Rossler system dynamical behavior , with the Lyapunov index theory to prove the existence of chaotic phenomena , numerical simulation of phase diagrams reveal the chaotic phenomenon exists in specific forms , global bifurcation diagram shows along with the change of the system parameters , system have dynamic characteristics that from period track to the chaotic through doubling bi -furcation sequences .System with different parameters of the bifurcation diagram shows that:when the pa-rameters change , the system have a similar change tendency , but the change of system parameters in dif-ferent directions , the system variable ranges are different .Using proportional and differential controller to control the chaos , when the control parameters is appropriate value , this method can be controlled system to the desired periodic orbit .The work to further improve study on dynamic behavior for Rossler system , for the chaotic behavior control and the practical application in engineering provides a theoretical basis .
