Modal Parameter Identification of Controlled Structures

Journal of Guidance, Control, and Dynamics, 1997
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.

Modal parameter identification using simulated evolution

AIAA Journal, 1997
A global optimization algorithm based on the Darwinian evolutionary theory is implemented for the identification of modal parameters of linear vibrating structures. The capability of the evolutionary search method in locating the global minimum among numerous local minima is demonstrated.
