摘要

摘要: 针对不同型号的捷联惯性导航系统(SINS, Strapdown Inertial Navigation System)测量量程及动态性能差异大,而常规标定方法难以提供多动态性信号激励的问题,提出一种利用离心机和转台对SINS进行整体标定的新方法.通过将转台安装在离心机上,调整转台姿态以及离心机旋转速度和旋转半径,可对SINS提供多范围、多运动形式的信号激励,实现对不同参数特性SINS的标定.建立了完整的离心机转台控制模型并对其进行了仿真验证,利用转台依次调整SINS到6个不同位置,控制离心机对每个位置进行正反两次共计12次旋转,即可标定出整个系统的24个误差参数.理论分析表明:该标定方法简单易操作,数据利用率高,激励信号设置灵活,具有一定的工程应用价值.

Abstract: Focusing on different types of strapdown inertial navigation system (SINS) having great difference on measuring range and dynamic performance, a novel SINS calibration method using centrifuge and turntable was proposed. The turntable was installed on the centrifuge. By adjusting the attitude of the turntable and the control parameter of the centrifuge, signals of different ranges and dynamic parameters would be generated, and this could be used for calibrating different SINS. The complete control models of the centrifuge and turntable were built and simulated. The SINS was rotated 12 times in six positions, and then 24 error parameters of SINS would be determined. The theory analysis shows that the new calibration method is simple and easy to be implemented, the calibration data has high-usage, and the output signals can be set flexibly. Therefore this method has some actual engineering value.
