Aiming at the black - box case that local kalman filters provide only the parameters and covariance matrices of filtered states , a novel multi - model adaptive estimator is designed on the basis of the united ci method 在前述保守最优数据融合算法基础上,针对局部kalman滤波模型只能给出滤波状态参数及其方差阵的情况,设计了一种新型的多模型( mm : multi - model )自适应估计器。
In statistics, an adaptive estimator is an estimator in a parametric or semiparametric model with nuisance parameters such that the presence of these nuisance parameters does not affect efficiency of estimation.
