Patent

CA 2236757

The invention is based on the use of the principles of Lange's Fast Kalman Filtering (FKF TM) for large process control, prediction or warning systems where other computing methods are either too slow or fail because of truncation errors. The invented method makes it possible to exploit the FKF method for adaptive Kalman Filtering of dynamic multiparameter systems with large moving data-windows.

L'invention est fondée sur la mise en application des principes du filtrage de Lange's, Fast, Kalman (FKF<TM>) pour des systèmes importants de commande de processus, de prédiction ou d'avertissement lorsque d'autres méthodes de calcul s'avèrent trop lentes ou échouent à cause d'erreurs de troncature. Le procédé objet de l'invention permet d'exploiter la méthode FKF, afin d'effectuer le filtrage adaptatif de Kalman de systèmes dynamiques à paramètres multiples comportant des fenêtres importantes de données mobiles.
