摘要

为了恰当地反映数字式涡流传感器的特性,本文首先介绍了其工作原理,并描述了被测试件位移量与相关测量电路输出频率之间的特征关系(d, f)。然后基于最小二乘估计算法的基本原理,利用MATLAB语言提出了一种数字式涡流传感器关系特征(d, f)的数学建模方法,并给出了建模程序流程图和仿真结果。

Realization of Numeral Eddy Current Sensor Modeling
In order to properly reflect the characteristics of numeral eddy current sensor, this paper begins with an introduction of its working principles, and the characteristic relationship(d, f) between the displacement amount of tested specimens and the output frequency of relative measuring circuits is also described. Then a mathematical modeling approach of numeral eddy current sensor relation feature(d, f) is proposed based on the basic principles of least squares estimation algorithm via the language of MATLAB, and the modeling program flowchart and the simulation results are provided as well.
