The main objective of this study is to propose a methodology to build a parametric linear model of Flexible Multibody Systems for control design. This approach uses a combined Finite Element - State Space Approach based on component modes synthesis and double-port approach. The proposed scheme offers the advantage of automatic assembly of substructures, preserving the elastic dynamical behavior of the whole system. Substructures are connected following the double-port approach; i.e, through the transfer of accelerations and loads at the connection points, which take into account the dynamic coupling among them. In addition, parametric variations can be included in the model for accomplishing integrated control/structure design purposes. The method can be applied to combinations of chain-like or/and star-like flexible systems, and it is validated through its comparison with the assumed modes method for the case of a rotatory spacecraft., This paper has been withdrawn by the author due to significant changes in the article's content
