Problems of Control and Informatics| Summary: | The behavior of Kalman filter is studied at interpretation of unknown initial conditions as the random variables having a covariance matrix proportional to large positive parameter. The developed approach permits to express characteristics of the filter in an analytic form, to explain phenomenon of divergence and suggest a limiting estimation algorithm which is independent of large initial parameter leading to divergence. As the application two problems — filtering with a sliding window and parameter estimation of separable regression are considered. The re-ceived results are illustrated by example of radial basic neural network training. |
