摘要
目前参数估计的方法很多,本文介绍用图解法进行参数估计,此法算式简单,能得到较好的参数估计,不存在收敛问题。
There are many methods of parameter estimation now. This paper introduces a graphical method of parameter estimation. The advantages of the method are that the algorithms are easy, a better numerical result is offered and no convergence problem exists.
