| 摘 要： | 首先介绍了时间序列ARMA模型及其建模方法,并利用该方法基于振动环式微机械陀螺的实测数据建立了振动环式微机械陀螺随机漂移的ARMA模型。在此模型基础上,设计了Kalman滤波器。仿真结果表明此方法能够有效抑制微机械陀螺的零点随机漂移。

| Abstract: | At first this paper gives an introduction to ARMA model and its modeling method.Then an ARMA model is established based on the measured data of a vibrating ring micromachined gyro.Finally,a Kalman filter is designed according to the established ARMA model.The simulating results demonstrate the effectiveness of this method. |
