...Jun Yu; Maura Imbimbo; Raimondo Betti In this paper, a methodology is presented for the identification of the complete mass, damping, and stiffness matrices of a dynamical system using a limited number of time histories of the input excitation and of the response output. Usually, in this type...

...Z. Y. Shi; S. S. Law This paper addresses the identification of linear time-varying multi-degrees-of-freedom systems. The identification approach is based on the Hilbert transform and the empirical mode decomposition method with free vibration response signals. Three-different types of time-varying...

...G. W. Reich, Mem. ASME, Aerospace Engineer,; K. C. Park, Fellow ASME, Professor A theory for structural system identification which utilizes strains and translational displacements as measured outputs is presented. The state variables of the fundamental first-order form consist of the strains...

... networks which possess a different sensitivity in the point where the identification error vanishes. For linear interpolation of the loading as well as the unloading data (LL) a strong effect of the nonlinear hardening can be observed, so that the determined value of ν increases for increasing...

... the reliability of the estimated changes involved in dealing with real-world (i.e., not noise-free) measurements that result in uncertain estimates of the physical changes in the article being monitored. [S0021-8936(00)03303-1] A summary of the identification results for the three systems is shown in Tables...
