摘要 分析了一个具有慢变参数的非线性系统,利用Melnikov方法,分析了系统在参数发生变化时的同宿分叉,同时利用分叉结果,数值地讨论了当系统参数发生变化时安全盆的侵蚀与分叉、混沌的联系。 This paper deals with a non linear system with slowly varying parameters. It studies the system's homoclinic bifurcations by the Melnikov method and discusses the erosion of safe basins numerically by the results of bifurcations when the control parameters of the system vary.
