IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThis paper presents a procedure for improving the transient response of a boundary-controlled nonlinear flexible elastic beam via a feed-forward action. It is shown that it is possible to obtain a formal analytic solution of an infinite-dimensional linear system, which approximates the nonlinear dynamics, under time-varying boundary condition in terms of the free vibration modes of the structure. The feed-forward action is then obtained by inverting the relationship between input and output.
