摘要 本文讨论常微分方程周期问题的一种数值求解方法。首先将常微分方程周期问题转化为等价的最优参数选择问题,通过研究最优参数选择问题的数值求解方法,得到常微分方程周期问题数值求解的一种新方法。最后,应用最优控制的软件Miser计算三个算例,验证了此数值方法的有效性。 The numerical methods for calculating periodic solutions of ordinary differential equations are considered. Firstly, the periodic solutions of ordinary differential equations are equal to optimal parameter selection problems are shown. By virtue of numerical methods for optimal parameter selection problems, a new numerical method for calculating periodic solutions of ordinary differential equations is obtained. At last, three numerical experiences are given to illustrate the validity of numerical methods.
