A spectral density approach for the identification of linear systems is extended to nonlinear dynamical systems usin incomplete noisy response measurements. A stochastic model is used for the uncertain input and a Bayesian probabilistic approa to quantify the uncertainties in the model parameters. The proposed spectral-based approach utilizes important statistical proper Fast Fourier Transform and their robustness with respect to the probability distribution of the response signal in order to… CONTINUE READING
