稳定非线性动力系统周期的计算机分析

Computer Analysis of Period of Stable Non Linear Dynamical System

提出采用后继函数法来确定非线性动力系统的周期．并编制计算机程序对ＶａｎｄｅｒＰｏｌ方程实例计算周期和绘制相图．结果表明，该方法计算结果准确且实用性强．本方法不但适合于求解保守系统和具有周期解非线性动力系统的周期。

Presents succeeding function method to decide the period of stable non linear dynamical system. Using the computer programme formed,the period of Van der Pol equation was correctly computed and its phase picture were drawn. The results are correct and valid. This method is not only suit for conservative system and limited disc non linear dynamical system with period but also applied to dissipative system.
