查询词典 stochastic filtering

The fourth chapter in this paper introduces the modeling ideas of stochasticvolatility into panel data model and puts forward panel data stochastic volatilitymodel. The Kalman Filtering can be employed to filter out the quasi-likelihoodfunction of the model and quasi-maximum likelihood estimation is used as achief means of estimating the parameter of the model.

Under the circumstances that some prior knowledge about the possible fault can be obtained,the dynamic behavior of the fault is proposed and used to solve fault estimation problem.While,if there is no extra knowledge available about the possible fault other than the condition of l_2 bounded,the residual generation is formulated into a problem of observer-based H_∞filtering problem in the sense of stochastic,and the linear matrix inequality approach to solve this problem is proposed.

对于能够了解部分故障先验知识的情况，提出描述故障结构特性的动态模型，解决H_∞故障估计问题；而当故障信息完全未知情况下，将基于观测器的残差产生器设计归结为随机意义下的H_∞滤波问题，提出了该问题求解的线性矩阵不等式方法。
