An application example for the B-spline based nonparametric system identification

The goal of this paper is to present a smoothing technique for the identification of systems whose frequency response function (FRF) is smooth. Using a generalized and modified B-spline based methodology an FRF can be estimated. With respect to the system dynamics, it can be possible 1) to reduce the disturbing noise 2) to decrease the effect of transients 3) to reduce the number of model parameters.
