摘要
本文论述液浮摆式力反馈平衡加速度计零位误差产生机理;分析了零位漂移数据的特点;提出在运用时序分析的DDS法基础上对零位漂移数据进行建模的方法。建立了自回归滑动平均模型并给出模型参数估计及置信区间,解析了模型参数的物理意义,利用此模型对加速度计零位漂移数据进行统计特性分析。
This paper describes a generation principles of zero-error for liquid suspension pendulum force feedback rebalance accelerometer. and analyses character of zero-drift data.presents a method that founding model of zero-drift data is based on utilizing DDS method of time series analysis.It has founded Autoregrecsive Moving model and given model parameters estimation and confidence interval, whereby physics meaning of model parameters is explained and statistical characteristic of zero-drift data analysed by utilizing this model.
