This paper is concerned with the identification of the modal parameters of structures. It is a well known result that, due to the presence of measurement noise, time domain identification methods often result in biased estimators. Several authors have proposed methods of noise filtering, often based

β¦ Synopsis
Kalman filtering is applied to the problem of System Identification by interchanging the roles of the state variables and the unknown parameters.
It is assumed that simultaneous operating records of the controls applied and the measured outputs of the plant are available, and that the records of the outputs contain noise. The theory is developed in continuous time and the advantages and limitations of analogue computational methods are discussed.

Some important extensions are made via time series analysis so that the time delay can be estimated accurately by the use of correlation analysis, even when the input to the identified plant is a common stationary signal and is correlated with the process noise.
