| 摘 要： | 本文研完惯性制导系统工具误差的自适应估计问题。运用自适应技术,这是解决制导精度鉴定问题的一个新的尝试,文中对仪表的误差模型给出了动态补偿,并给出了误差系数的递推估计。对模型中随机量的统计特性应用了自适应技术,并对岭回归引入了自适应估计,对滤波过程中模型的辨识及估值中偏倚的补偿,进行了讨论。

| Abstract: | This paper studies the problems of adaptive estimation of the instrumental error to the guidance system. In the first, we establish the dynamic compensation model of the instrumental error and give recursive estimators of the error coefficients. When the statistical characteristics of the random error are unknown, we suggest to apply the adaptive estimation method and using this method to construct ridge estimation of the parameters. In the same time, the identification of the model and the compensation for the biased estimator are discussed. |
