Paper Abstract

A method for using the extended Kalman filter to identify the modal parameters of vibration controlled structures has been developed and demonstrated. The closed-loop structural vibration system is excited by a known of unknown excitation signal and the resulting time histories of the closed-loop systems response are analyzed. The present method has the advantage that the physical parameters of the system are directly estimated. The numerical examples showed excellent results and it is expected that the present method can be applied to the on-orbit modal testing of controlled space structures.
