摘要
针对离散混沌系统有时会出现多个参数同时参与系统行为的情况,提出了多参数离散混沌系统的一般形式表达式。对于多参数离散混沌系统,如果确定了不同的系统参数,混沌系统的一般形式可转化为相应的混沌系统。通过对多参数离散混沌系统的动力学行为分析,发现同一离散混沌系统在多个参数的影响下,会出现复杂的动力学行为。给出了分岔序列的具体计算方法和步骤,数值模拟实验表明该方法的正确性和有效性。
There is not only one system parameter in a discrete chaotic system. The dynamics model of multi-parameter discrete chaotic systems is suggested. The different discrete chaotic systems can be obtained by defining different system parameters. And as can be seen from the analysis of the dynamic behavior of multi-parameter discrete chaotic system, at the effect of multi-parameters, complicated dynamic behavior and bifurcation series in the same discrete chaotic system will appear. The calculation method of bifurcation series is studied, the simulation results prove the correction of the method.
