Description: 提出了微惯性测量单元( MIMU) 在高动态、高过载复杂应用条件下的误差整机标定和补偿方法。首先, 建立了高动态, 高过载复杂应用条件下MIMU 的误差模型, 该模型包括了结构误差, 传感器安装误差和MEMS 惯性传感器在复杂条件对精度影响较大的误差项, 指零位温度漂移、互耦误差、刻度因子非线性和微陀螺加速度效应误差; 根据模型提出了整机标定补偿方法, 该方法可以标定MIMU 的63 个误差系数, 并且不需要对单个传感器进行标定。然后, 介绍了利用最小二乘法对模型进行误差系数标定的方法和步骤, 并对自研的MIMU 进行了标定。(T he entire calibrat ion and compensat ion metho d o f a Miniature Inerial Measur ement U nit( MIMU) in high dy namic and o verload complicate environments w as pr opo sed. First ly, an error model applied to the complicate applicat ion environment s w as established, which consist s o f the structureer rors, installatio n misalignment errors and the erro rs of the MEMS sensors including zero outputdrif t, temperature drif t , crossax is error, no nlinear scale factor erro r and acceler at ion effect err or of
