捷联惯性导航加速度计动态误差模型在三轴转台上的实验标定

The Experimental Calibration on Three-Axis Turntable of Strapdown Accelerometer Dynamic-Error-Model

本文提出了在三轴转台上用双轴速率输入法来估计捷联惯导加速度计动态误差模型参数的方法。该方法基本解决了加速度计动态误差的标定问题,同时也容易实现试验计划的优化设计,以提高模型参数辨识精度。所做工作对于提高捷联惯性导航系统精度、丰富惯性器件测试理论及开发三轴转台的使用功能均有一定意义。

In this paper an experimental method using biaxes - rate - in- put is provided to determine the parameters of strapdown accelerometer dynamic- error-model. This method basically solves the calibration problem of accelerometer dynamic-error,and is convenient to achieve the optimal experimental design which can increase the identification accuracy of model - parameters. The study we have done is useful for increasing the accuracy of strapdown inertial system, enriching the inertial - components test theory and developing the utility of three - axis turntable.
