Abstract : Time varying parameters appearing in a dynamic system are estimated on-line using an adaptive extended Kalman filter. Two distinct schemes for adaptive filtering are considered, based upon the alteration of the predicted error covariance matrix according to the difference between the size of the observed residuals and their predicted values. Results are presented for the identification of the frequency and damping of time varying second order systems. (Author)
