摘要
本文对求解拉氏逆变换遇有多重极点情况,提出了一种简易解法,即对s域函数只需通过“一次长除”运算,便可直接确定各阶因式的系数K_i值,从而避免了求解高阶导数的繁琐运算,因此不失为一种较好的简便方法。
In this paper, a simplified method for solving the Laplace inverse transformation with multiple poles is presented. In the v domain. coefficients K_i of every order fractions of a function would be determined directly by means of polynomial division without calculating high order derivetives. and therefore it is a brief method.
