Modal Parameter Identification of Controlled Structures
Copyright policy )Modal Parameter Identification of Controlled Structures
A simple procedure to extract the modal parameters of the closed-loop structural system is proposed. It is formulated by using the extended Kalman filter (EKF) technique. The unknown parameters are eigenfrequencies, damping ratios, mode shapes, and modal masses. The initial values needed in the EKF calculation are supplied by the finite element method preanalysis.
