基于参数随机化的Rossler系统的混沌特征

Chaotic Characteristic of Rossler System Based on Parametric Randomization

在经典Rossler系统的基础上,考虑系统参数以一定的概率在混沌区间和非混沌区间取值,得到参数随机化的Rossler系统。数值结果表明,参数随机扰动下的Rossler系统仍然存在混沌现象。

On the basis of the classical Rossler system,the systemparameters are considered to take value in the chaotic interval and thenon-chaotic interval according to a certain probability,and then the parametersrandomized Rossler system is obtained.Numerical results show that chaotic phenomenastill exist in Rossler system under random disturbance of parameters.
