| الوصف: | A field of current interest in space technology is the on-orbit operation concept, often requiring that a chaser spacecraft captures and berths a target spacecraft. The physical link connecting the two satellites is usually characterized by a high degree of flexibility, because of the special requirements imposed to the space systems, in particular the constraints on the mass at launch. The focus in this paper is in the study of an attitude control of the paired platforms system such that the elastic oscillations do not interfere with the attitude dynamics, and the final configuration is reached without residual vibrations. At the scope, a rest-to- rest techniques is applied, requiring an accurate description of the dynamic model of the connected satellites system as a flexible multibody setup. The results of this control are first tested by means of a numerical tool, simulating nominal and non-nominal scenarios. Then it is applied to an experimental test-bed, consisting of two free - floating platforms connected by means of an elastic joint. The performance of the rest-to-rest technique is compared to other classical control laws aiming to minimally excite the system undesired dynamics, showing a promising superiority |
