摘要
采用时间序列分析理论,通过实测数据对三浮陀螺的随机漂移建立了自回归滑动平均(ARMA)模型,详细探讨了数据处理与模型建立的过程。利用MATLAB设计了建模软件,减轻了数据计算的工作量,并分析了相关结论。结果表明,模型能准确反映陀螺漂移的特性。
Based on the measured data and time-series analysis theory,an ARMA model of the random drift of liquid floated gyro is presented.The process of the modeling of the gyro drift and the data processing are investigated in the paper,and the corresponding results are given.The software served for modeling is designed by using MATLAB,thus the data calculation is reduced effectively and the results were analyzed.The results show that the model can accurately reflect the characteristics of gyro drift.
