Librational Controller Design for a Tethered Satellite System during Orbital Maneuvering

A controller is designed to restrain the in plane libration of a tethered satellite system (TSS). To stabilize the in plane subsystem of TSS, a hierarchical iterative nonlinear sliding mode control is proposed. The stability of the closed loop system is also proved. The validity of the proposed algorithm is demonstrated by numerical simulation results. Moreover, the advantages of the algorithm are presented via comparing with the traditional hierarchical sliding mode control.
