| 摘 要： | 本文依据描述函数法分析非线性系统之原理,运用 BASIC 语言,提出了非线性系统计算机辅助分析程序设计方法。文中涉及了五种典型非线性特征。运用此法编制的程序,能够判断系统在不同初始条件下的稳定性;如果系统存在自持振荡,则给出自持振荡的振幅和频率。同时,为使系统分析形象直观,在屏幕上进行了作图,并显示了分析结果.

| Abstract: | This paper proposes a program designing method in BASIC Language,to the principle of the describing function method.Five typical nonlinear characteristics are mentioned in the paper.The program so designed can be used to determine the stability of the system in different initial conditions.If self-contained,oscillation exists in the system,it will provide the amplitude and frequency of the oscillation.At the same time,in order to make the system analysis display more picturesque and diirect,a graph can be set up on the screen to gether with the results of the analysis. |
