The control of in-plane transversal vinrations of a tethered satellite system by means of a longitudinal force exerted by subsatellite thrusts is analysed. A one-mode model is derived for describing the in-plane dynamics of such a system. On the basis of this model, two different non-linear (and simple to be implemented) control laws are proposed for the stabilization of the tethered satellite system. The Lyapunov stability theory is used to show the global 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.

Abstract
The control of in-plane transversal vinrations of a tethered satellite system by means of a longitudinal force exerted by subsatellite thrusts is analysed. A one-mode model is derived for describing the in-plane dynamics of such a system. On the basis of this model, two different non-linear (and simple to be implemented) control laws are proposed for the stabilization of the tethered satellite system. The Lyapunov stability theory is used to show the global 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
