| 摘 要： | 三轴磁通门传感器应用较为广泛,但非正交误差和非水平误差影响了三轴磁通门传感器的磁场测量精度.根据三轴磁通门传感器测量原理,分析了非理想条件下与理想条件下磁场转化矩阵关系.为消除三轴磁通门传感器中非正交误差和非水平误差的影响,建立了以磁场转化矩阵参数为自变量的优化模型.采用全局优化能力强、寻优效率高的微分进化算法求解该优化模型,求得磁场转化矩阵参数即可实现非正交误差和非水平误差的同时修正.三轴磁通门传感器误差修正实验表明,该方法在一定程度上可有效消除三轴磁通门传感器中非正交误差和非水平误差的影响,对提高三轴磁通门传感器磁场测量精度具有重要意义.

| Abstract: | Triaxial fluxgate magnetometers are widely used to measure magnetic field in engineering,but the magnetic field measurement precision is influenced by the non-orthogonal error and non-horizontal error.According to the measurement principle of the triaxial fluxgate magnetometer,the realationship of the magnetic field transformation between the ideal and nonideal triaxial fluxgate magnetometer was analsized.In order to eliminate the non-orthogonal error and non-horizontal error,the optimization model regardin... |
