Abstract

A Kalman filter algorithm has been developed to estimate the amplitude, phase and their derivatives of the first four modes of vibration of a composite structural element. The filter input is provided by a single measurement of integrated strain within the beam, which is obtained from an embedded fiber optic interferomethc sensor.
