摘要
针对高旋弹用MEMS-IMU在传统标定方法中不能全面激活误差,且存在标定流程复杂、标定效率低的问题,设计一种高旋弹用MEMS-IMU自动标定系统和方法。首先分析了高旋弹用MEMS-IMU输出特性,构建误差模型,设计十二位十八速的标定方案,并优化转台转动方案。通过自动标定系统,实现高旋弹用MEMS-IMU的自动标定。实验结果表明,该方法能实现对高旋弹用MEMS-IMU的自动标定,MEMS陀螺仪滚转、俯仰和偏航轴精度较传统方法分别提升98%,72%,73%以上;MEMS加速度计三轴精度分别提升53%,47%,7%,同时整个标定流程时间大幅减少,提高了标定效率。
In the traditional calibration method,the MEMS-IMU for high-speed rotating projectiles cannot fully activate the error,and the calibration process is complex and the calibration efficiency is low.To solve the problems,this paper designs an automatic calibration system and method of the MEMS-IMU for high-speed rotating projectiles.Firstly,the output characteristics of the MEMS-IMU for high-speed rotating projectiles are analyzed,an error model is constructed,a twelve-position,eighteen-speed calibration scheme is designed,and the turntable rotation scheme is optimized.Through the automatic calibration system,the automatic calibration of the MEMS-IMU for high-speed rotating projectiles is realized.The experimental results show that the proposed method can achieve the automatic calibration of the MEMS-IMU for high-speed rotating projectiles.Compared with that of the traditional method,the accuracy of MEMS gyroscope on roll,pitch and yaw axes is improved by more than 98%,72%and 73%respectively,and the accuracy of MEMS accelerometer on the three axes is improved by 53%,47%and 7%respectively.The duration of the whole calibration process is greatly reduced,which improves the calibration efficiency.
