| 摘 要： | 模拟了Willamowski-R(o)ssler化学系统经倍周期分岔进入混沌,以及由混沌退化到周期态的全过程.给出了分岔图与最大Lyapunov指数谱和庞加莱截面及功率谱和返回映射图,仿真结果揭示了该系统混沌行为的普适特征.设计了自适应控制器和非线性控制器,通过理论分析及数值仿真实现了对其无量纲化系统的控制.采用驱动-响应的同步方法实现该系统的全局指数同步,数值仿真结果表明该方法是有效的.

| Abstract: | The whole process of the change of Willamowski-Rrssler chemistry system from period motions to chaotic motions through double-period bifurcation,as well as the change from chaotic motions to period motions.We present bifurcation diagram,Lyapunov exponent spectrum,Poincare section,power spectrum and return map of the system,and the chaotic behavior of the model is also revealed.The adaptive and nonlinear controllers are designed,and the theoretical analysis and numerical simulation show that the chaos of the non-dimensional form of Willamowski-R(o)ssler system can be controlled effectively.Drive-Response method is used to realize the global exponential synchronization.The simulation results show that the Drive-Response method is effective. |
