| Abstract: | Described in this paper are three new approches for the parameter identification of a vibrating system, devoted to improve the accuracy of identifying modal and physical parameters from measurements with noisy signals and to identify the distributed structural parameters directly from response signals without resort to applied force information. The techniques presented here-in are the Maximum Likelihood Method, the Prony Identification Algorithm, and the Finite Element Inverse Method. |
