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.
EnglishThe paper deals with asymptotic tracking of a reference attitude trajectory for rigid spacecraft. Based on differential equations that describe the error dynamics with respect to a given reference trajectory, the design procedure is formulated as a stabilization problem. Both gas-jet and reaction-wheel control modes are considered. Under mild smoothness assumptions on the reference trajectory, a nonlinear digital controller is proposed based on a multirate control strategy. Simulation results show the effectiveness of the proposed digital control scheme.
