光纤陀螺仪漂移值产生原因十分复杂,具有非线性和随机性变化特点,结合光纤陀螺仪的漂移值误差变化的特点,提出一种数据挖掘的光纤陀螺仪的漂移值误差分析方法,首先采用经验模分解(EMD)对光纤陀螺仪的漂移值序列进行分解,然后分别采用极限学机和相关向量机分别对随机波动序列和趋势序列进行预测,最后对它们预测结果进行加权,得到光纤陀螺仪的漂移值预测值,并将该方法应用于具体的某光纤陀螺仪漂移值误差分析中,结果表明,本文方法的光纤陀螺仪漂移值预测精度达到95%以上,预测结果为光纤陀螺仪的寿命研究提供了有价值的参考依据。
The reason of the drift value of optical fiber gyroscope is very complicated, with the characteristics of non-linearity and randomness. Based on the characteristics of the error of optical fiber gyroscope, a method of error analysis of drift value of optical fiber gyroscope is proposed. Firstly, (EMD) is used to decompose the drift value of optical fiber gyroscope. Then, the limit fluctuation and related vector machines are respectively used to predict the random fluctuation and trend sequences. Finally, the results of the prediction are weighted to obtain the optical fiber gyroscope The results show that the prediction accuracy of the optical fiber gyroscope drift of this method is more than 95%, and the prediction result is the research on the life of optical fiber gyroscope Provide a valuable reference.
