摘要

为了正确反映霍尔式微位移传感器的特性,本文首先介绍霍尔式微位移传感器的工作原理,得出霍尔式微位移传感器被测试件位移量与相关测量电路输出电压(S,V)关系特征,然后基于最小二乘估计算法基本原理,提出了运用MATLAB语言建立霍尔式微位移传感器(S,V)关系特征的数学模型的方法,给出建模的程序流程图以及仿真结果.%In order to properly reflect the characteristics of Hall micro-displacement sensor, this paper begins with an introduction of its working principles, and the characteristic relationship (S, V) between the displacement amount of tested specimens and the output voltage of relative measuring circuits is also described. Then a mathematical modeling approach of Hall micro-displacement sensor relation feature(S, V) 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.
