基于自适应遗传算法的三轴磁强计误差校正方法
Calibration for Tri-Axial Magnetometer Based on Adaptive Genetic Algorithm
摘要
Abstract
Tri-axial magnetometers are widely studied and used in geomagnetic measurement. The influence on the measurement results caused by tri-axial nonorthogonality is analyzed,and the calibration formula is established. An optimization mathematical model is established to get the nonorthogonal error angles, and the Adaptive Genetic Algorithm is used to solve the model,in order to achieve the identification of intrinsic parameters and the calibration of measurement errors. The measurement experiment of FGM-2000 tri-axial magnetometer is done to verify the calibration method,and results show that the effect is obvious,the measurement error is reduced 88. 1% and the measurement accuracy is significantly improved.关键词
