一个具有不确定性观测的滤波问题

A filtering problem with uncertainty in observation

Shaolin Ji, Chuiliu Kong, Chuanfeng Sun

摘要:

研究了一类广义卡尔曼-布西滤波模型及其在模型不确定性下的鲁棒性问题。我们发现这个鲁棒问题等价于考虑一个次线性算子下的估计问题。因此,我们转向次线性算子下的最小均方估计。利用Girsanov定理和极大极小定理,得到了信号过程$x_{t}$在给定时间$t\in\lbrack0,T]$的最优估计$\hat{x}_{t}$.

英文摘要:

This paper is concerned with a generalized Kalman-Bucy filtering model and corresponding robust problem under model uncertainty. We find that this robust problem is equivalent to considering an estimate problem under some sublinear operator. Therefore, we turn to obtaining the minimum mean square estimator under a sublinear operator. By Girsanov theorem and minimax theorem, we obtain the optimal estimator $\hat{x}_{t}$ of the signal process $x_{t}$ for given time $t\in\lbrack0,T]$.
