Identification of Equivalent Linear Parameters of Nonlinear System by Extended Kalman Filter

Abstract

This study deals with a numerical method for equivalent linear identification of nonlinear systems with the help of the extended Kalman filter, where a technique of local iterations of the filter by Hoshiya et al. is applied to attain efficient identification of nonlinear behavior of systems. A bilinear histeretic restoring system is numerically analyzed to demonstrate the accuracy of the method.
