为了更好地解决工程实际中三浮陀螺极轴伺服测试时误差系数估计问题,采用了Kalman滤波和递推最小二乘的方法。试验结果证明,Kalman滤波方法能够有效地估计出极轴伺服测试时的陀螺误差系数。用统计检验的方法分析了该模型以及各系数的显著性,结果显示对D_(vz)和D_(zz)的估计是显著的。 In order to solve the problem of error coefficient estimation of the three-floating gyroscope polar axis servo test in engineering practice, Kalman filtering and recursive least squares method are used. The experimental results show that the Kalman filter method can effectively estimate the gyroscopic error coefficient of the polar axis servo test. The statistical analysis of the model and the significance of the coefficients show that the estimates of D_ (vz) and D_ (zz) are significant.
