SYSTEM IDENTIFICATION WITH CONSTRAINT FOR INCORPORATING APRIORI KNOWLEDGE

摘要

PROBLEM TO BE SOLVED: To provide a system identification method for improving an initial parametric model of a system by incorporating apriori knowledge of the system. SOLUTION: The initial parametric model of the system includes a plurality of parameters based on analysis of a plurality of inputted signals and a plurality of outputted signals. The method has a step for executing parametric optimization with constraint of the system based on the initial parametric model and a determined set of constraints and for generating the improved parametric model of the system after determining the set of constraints based on the apriori knowledge corresponding to a plurality of sets of parameters. The plurality of inputted signals and the plurality of outputted signals are not included in the parametric optimization with constraint of the initial parametric model. COPYRIGHT: (C)2004,JPO&NCIPI
