動態(tài)測量中傳感器非線性擬合方法

從壞值概率分析基礎上提出了動態(tài)測量中傳感器數(shù)據(jù)的壞值剔除方法,用可靠的數(shù)據(jù)代替剔除的壞值,為后續(xù)的傳感器數(shù)據(jù)處理保證了數(shù)據(jù)的合理性,如傳感器的非線性擬合。并通過對動態(tài)測量中某霍爾位移傳感器位移- 電壓數(shù)據(jù)進行了壞值剔除和三次多項式非線性擬合,表明動態(tài)測量中傳感器數(shù)據(jù)的非線性處理方法。

Abstract : After analysis the probability of abnormal data , a method erasing the abnormal data of non - linear sensor in dynamic measurement is given.Based on the method ,the abnormal data is replaced by reliable one ,and curve fitting method is given to deal with the processed data. The curve of a Hall2displacement sensor is obtained by polynomial fitting. The method of data2erasing and curve2fitting can be applied in processing the data of sensor
in dynamic measurement .
Key words : non2linearity ; abnormal data erasing ; dynamic measurement ; curve fitting
