"Method for fast K- filtering in large dynamic systems"

Inventor: Lange, Antti A. I.
Abstract:
The invention is based on the use of the principles of Lange's Fast K- Filtering (FKF) 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 dynamic multiparameter systems that are governed by partial differential equations.
