陀螺仪短周期性能测试方法研究

讨论了陀螺仪短周期重复性能的标定测试方法，即极轴翻滚试验方法。该方法以地球极轴为基准，通过对一周过程的电流值进行离散傅立叶分析，经过相应的运算处理求出误差模型参数的估计值。试验结果表明，该方法辨识参数多，全面反映了陀螺仪性能，可以科学地考察陀螺仪的短周期重复性。

Study on the Method of the Short-period Performance for the Gyroscope

The method of calibrating and testing of the short-period repeatability of gyroscope is discussed,which is also called the polar-axis tumbling method.On the base of the earth polar-axis,through discrete Fourier analysis of the value of one circuit electric current,the parameters of the error model are estimated by the corresponding calculation.Experimental results show that the number of parameters estimated by the method is more than others,and the performance of the gyroscope can be reflected fully,therefore the short-period repeatability of gyroscope can be verified scientifically.
