摘要

高精度的误差系数可准确评价加速度计的精度与性能

从石英挠性加速度计误差模型入手

对其进行多方向振动测试试验

利用总体最小二乘（TLS）算法辨识加速度计模型方程中的高阶误差系数

建立较高精度的加速度计数学误差模型。为验证算法的有效性及所实施试验的可靠性

和传统重力场多点测试辨识加速度计参数方法作对比

同时

提出误差系数和决定系数两个指标来评价振动测试的辨识效果。结果表明:采用多方向振动测试结合总体最小二乘算法方案所辨识出加速度计高阶误系数精度较高

在实践中具有较好的借鉴意义。

Abstract

High precision error coefficients can accurately evaluate performance and precision of accelerometer

start from quartz flexible accelerometer error model

multi-directional vibration test experiments are carried out and by total least squares（ TLS） algorithm to identify higher-order error coefficient in accelerometer model equation

establish high precision accelerometer mathematical error model. To verify effectiveness of algorithm and reliability of implemented experiment

taking the traditional multi-point gravity field test accelerometer parameter identification method for comparison

at the same time

put forward error coefficients and determination coefficients indicators to evaluate the effect of vibration test identification. The result shows that accelerometer higher order error coefficient identified by total least squares method combined with multi-directional vibration test has higher precision

and has good reference in practice.
