惯性加速度计横向灵敏度测量方法及特性分析

The Test Method and Analysis on Characteristic of Inertia Accelerometer Transverse Sensitivity

随着现代武器打击精度的提高,加速度计的横向输出误差对惯性导航系统有着一定的影响,所以研究加速度计的横向灵敏度可以有效地提高武器的导航定位精度。文中主要介绍了离心法测量横向灵敏度,采用以DSP控制器为核心的运动控制系统来确保离心机的稳速控制,介绍了两种离心机测量横向灵敏度的方法并将测试结果用Matlab分析处理。

With the enhancement of modern weaponry＇s hit precision, the transverse output error of accelerometer brings about an effect to inertial navigation system, so study the accelerometer transverse sensitivity can enhance the weaponry＇s navigation accuracy. A brief introduction about testing transverse sensitivity with centrifuge was introduced. In order to insure the speed stability control of centrifuge adopted motion control system that take DSP controller as core, and two kinds of method about how to test transverse sensitivity with centrifuge were introduced and the result was analyzed with Matlab.
