CINECA IRIS Institutional Research Information System
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.
EnglishActive suspensions of advanced vehicles allows the active rejection of external disturbances exerted directly on the sprung mass of the vehicle and due to the road surface irregularity. We focus on the road irregularity disturbances with the purpose of isolating the chassis from vibrations transmitted through suspensions. The paper is aimed at the synthesis of a decoupling control law of the regulated outputs, i.e., roll, pitch and chassis height, from the external disturbances. The framework throughout is the geometric approach to the control of dynamic systems. It will be shown that a controlled and conditioned invariant subspace exists and this allows the perfect disturbance localization by feeding back the suspensions heights.
