一种加速度计的标定补偿方法研究
A Study on Calibration-Compensation Method for Accelerometer
摘要
Abstract
Aiming at the problem that because of fixing error of the 3-axis accelerometer installed in the micro iner?tial measurement unit(MIMU)will enlarged in harsh cone movement situation,this paper puts forward a calibration-compensation method which is based on multi-position static rotation of the 3-axis position speed turntable. Accord?ing to the establishment of the angle error compensation model to design the completed experiment process of cali?bration,and finally,calculating calibration factor matrix and accelerometer's zero voltage accurately based on the method of nonlinear fitting data processing. according to the calibration experiment and error calculation contrast , this error of calibration method is one order of magnitude smaller than the previous one,improving the output accu?racy of the accelerometer effectively,having significant engineering application meaning.关键词
