一类适用于陀螺随机漂移预报的非线性模型

A Non-Linear Model Suitable for Gyro Random Drift Forecast

本文针对陀螺随机漂移的弱非线性和非平稳性,提出了一种多项式NAR模型及其辨识方法。对陀螺随机漂移测试数据的仿真表明,该模型能很好地用来预报陀螺随机漂移。

To counter weak non-linear and nonstationary characteristics of gyro random drift,a polynomial NAR model and its identification is proposed in this paper. Digital simulations have shown that the model can be applied to forecast gyro random drift well.
