| 摘 要： | 陀螺随机漂移是衡量陀螺仪精度的重要指标之一,对陀螺的随机漂移进行辨识与建模研究可对随机漂移作一定的补偿,提高陀螺的精度。利用小波多分辨率分析和假设检验的方法,在对某型压电陀螺随机漂移的实测数据进行预处理的基础上建立了时间序列模型,并在计算机上对卡尔曼滤波补偿随机漂移进行了仿真,结果证实了该模型的有效性。

| Abstract: | Random drifting is an important index of piezoelectric gyroscope. Research on the modeling of gyroscope could compensate the random drift to a certain extent and improve the accuracy of the gyroscope. Using multiresolution analysis of wavelet and hypothesis testing, the time sequence model of random drifting was founded. Af- ter filtering using Kalman approach, the variance of random drifting was obviously declined. The simulation results verified the efficiency of the model. |
