Projection-based Identification in the Frequency Domain

Identification in the Frequency Domain

This article reviews techniques to identify the frequency domain properties of linear and nonlinear systems from measured physical input/output data. Practical spectral analysis procedures are discussed that are valid with random data to predict the frequency response functions in single-input/single-output (SI/SO) linear models and in multipleinput/single-output (MI/SO) linear models. Special ...

Projection-based, frequency-domain estimation of superimposed translational motions

In this paper a description is given of a computationally efficient algorithm, based on the two-dimensional fast Fourier transform (FFT), for the estimation of multiple translational motions from a sequence of images. The proposed algorithm relies on properties of the projection (Radon) transform to reduce the problem from three to two dimensions and is effective in isolating and reliably estim...

Mixed Time/Frequency-Domain Based Robust Identification

A new robust identification framework that incorporates both time and frequency domain data is proposed. ¹his framework avoids situations where a good data fit in one domain leads to poor fitting in the other. Abstract—In this paper we propose a new robust identification framework that combines both frequency and time-domain experimental data. The main result of the paper shows that the problem...
