摘要
从时变观点出发,首次采用自适应Kalman滤波器解决原子钟状态最优估计问题,根据所设置的两种滤波器,对模拟钟及商品铯钟作了状态估计和预测的分析对比。结果表明,自适应Kalmau滤波器有效地纠正了普通Kalman滤波中出现的系统偏差,与Kalman滤波器相比它具有更优的跟踪性能和收敛性能。
In this paper we have solved the problem of optimal estimation for atomicclock state from the time-varying view by adopting adaptive Kalman filter for thefirst time. Based on two devised filters, analyses and comparasion of state estima-tion and prediction between simulant clock and commercial cesium beam clock havebeen carried out. The results show that adaptive Kalman filter corrects effectivelythe systematic departure in Kalman fileriing, with better performance of tracingand convergence, compared with kalman filter.
