Estimation of Modal Parameters and their Uncertainties [PDF]
, 1999 In this paper it is shown how to estimate the modal parameters as well as their uncertainties using the prediction error method of a dynamic system on the basis of uotput measurements only. The estimation scheme is assessed by means of a simulation study.
