摘要
给出了差分方程在工程实现过程中不收敛问题的解决方案。首先介绍了工程实现时如何将传递函数转化为差分方程;然后介绍了如何在差分方程中分析运算误差造成的影响;最后用级数方法分析了如何控制运算误差,才能使差分方程的结果收敛。
This paper gives a solution for the convergence of the difference equation in the process of engineering imple- mentation.First,this paper introduces how to transform the transfer function into a difference equation,then introduces how to analyze the effect of operational error in the difference equation.At last,this paper analyzes how to control the operation error by series method,so as to converge the result of the difference equation.
