摘要:

本文首先详细分析了PID控制器算法的基本原理,尤其是数字式PID控制器中的增量式PID控制器,论文从分析其基本原理出发,详细阐述了增量式PID控制器算法的实现过程;本文还采用一种拉普拉斯反变换的近似算法:Stehfest算法,将S域的拉普拉斯表达式F(s)近似转换为时域的函数表达式f(t),最后采用MSChart控件将f(t)显示出来,完成PID控制系统的仿真,经实验,最终取得满意的结果。

This paper has a detailed analysis of the basic principle of the PID controller algorithm, especially the incremental digital PID controller. Starting from the analysis of its basic principle, the paper expounds the process of the implementation of the incremental PID controller algorithm; this paper also adopts an approximate algorithm of inverse Laplace transform—Stehfest algorithm, which converts S domain Laplace expressions F(s) of time domain f(t) in an approximate method. Finally the MSChart control will display the image of f(t), completing simulation of PID control system. According to the experiment, the program has achieved satisfactory results in the end.
