摘 要 ：分段线性插值算法是一种技术比较成熟、实现比较简单的低次多项式插值算法,其曲线逼近程度即插值函数与原函数误差基本满足一般的工业控制场合需要.该算法占用系统资源少,在数据采集和数据处理等工业控制领域,往往使用单片机或嵌入式系统等资源受限处理器,通过分段线性插值算法简化原函数,减少计算量,对于提高系统整体性能具有显著的现实意义.

Abstract: Piecewise linear interpolation algorithm is a relatively mature technology and a relatively simple low-order polynomial interpola tion algorithm, the curve approximation degree of the interpolation function and the original function basically meet general industrial con trol applications need. The algorithm occupies less system resources in industrial control field such as data acquisition and data processing, es pecially in the system based on a microcontroller or embedded system and so on. Using piecewise linear interpolation algorithm to simplify the original function and to reduce the putation, it has significant practical significance for improving the overall performance of the sys tem.

程序主要部分包括两部分：单区间线性计算和全程线性插值计算.部分代码如下所示.单区间线性计算：

Char liner_seg_x8_y8(char xn,char x1,char x2,char y1,char y2)

{int yn,

Char tmp,

If(xn

{yn等于y1}

Else if(xn>x2)

{yn等于y2}

Else

{ If(y1

{yn等于y2-y1,tmp等于xn-x1,yn等于yn*tmp,tmp等于x2-x1,yn等于yn+(tmp/2),yn等于yn/tmp,yn等于y1+yn,}

//实现yn等于y1+(y2-y1)*(xn-x1)/(x2-x1),

Else

{yn等于y1-y2,tmp等于xn-x1,yn等于yn*tmp,tmp等于x2-x1,yn等于yn+tmp/2,yn等于yn/tmp,yn等于y1-yn,}

//实现yn等于y1-(y1-y2)*(xn-x1)/(x2-x1),}

return((char)yn),}
