摘要
为了提高颗粒检测实验的精度,使测量的数据更加准确,需建立颗粒粒径分布软测量模型。通过改进最小均方算法,测量多个波长下的消光值来获得待测颗粒系的粒径分布曲线,着重分析Mie散射的原理,计算消光系数矩阵。与多种反演算法进行比较,并且加入不同的噪声,验证最小均方算法的实验数据精确度较高。
In order to improve the precision of particle detection experiment and make the measured data moreaccurate,this paper establishes soft sensor model of the particle size dis tribution.This paper measures the lightextinction data at multi-wavelengths to obtain the particle size distribution curve of the particle system to be measuredby improving the least mean square algorithm,focuses on the analysis of the principle of MIE scattering,calculates theextinction coefficient matrix.Different degrees of noise and various of inversion algorithms are added to compare toprove that the least mean square algorithm has high precision in the experimental result.
