Uncertainty of models in intelligent systems under stochastic loading

Summarization: In this paper, we address the problem of vibrations of intelligent structures. Stimuli may come from external perturbations of the system, disturbances or excitation that may cause structural vibrations, such as wind loading or earthquake. First, an accurate model of a piezocomposite intelligent structure with special boundary conditions is derived by using of FEM analysis. Then the robustness of the uncertain closed-loop model performances has been investigated. Obtained results show the higher performance of Hinfinity design approach in rejection of disturbances.Παρουσιάστηκε στο: 7th European Congress on Computational Methods in Applied Sciences and Engineerin
