โœฆ Synopsis

The control of in-plane transversal vibrations of a tethered satellite system by means of a longitudinal force exerted by subsatellite thrusts is analyzed. A one-mode model is derived for describing the inplane dynamics of such a system. On the basis of this model, two different nonlinear (and simple to be implemented) control laws are proposed for the stabilization of the tethered satellite system. The Liapunov stability theory is used to show the g,lobal asymptotic stability of the station-keeping phase of the tethered satellite system, subjected to either control laws. The effectiveness of the proposed control laws is shown by means of both analytical arguments and simulation runs.

This paper.deals with the non-linear dynamics of a tethered satellite system, with particular reference to periodic transverse oscillations. The motion is governed by two integro-differential equations with quadratic non-linear terms associated to gyroscopic forces. Notwithstanding the weakness of t

A method of damping structural vibrations using optimization techniques is presented and applied to a tethered satellite system. Such systems show large displacements and require active or passive damping mechanisms. A tethered satellite system is modelled by the method of multibody systems using sy
