陀螺的多变量测试、相关分析和系统辨识

Gyroscope Multivariable Testing, Correlation Analysis and System Identification

本文通过对陀螺内部的某些状态变量和有关的环境变量与陀螺输出量进行同步测试,然后对采集的数据进行统计性预处理和相关性分析,最后利用相关函数进行误差响应模型辨识,从而找出它们与陀螺漂移的关系,为进一步提高陀螺的精度提供依据。

The different state variables of gyroscope are tested by a test system synchronously with software and hardware. And the sampled data of different state variables are processed through statistical anticipation,correlation analysis and spectrum analysis. Finally the discrete system is identified by using the related function. So the relation between the different state variables and the gyroscope drift can be found to provide the basis for improving the gyroscope accuracy.
