Nonlinear feedback deployment and retrieval of tethered satellite systems Academic Article uri icon


  • The Lyapunov approach for controller design is applied to the tethered subsatellite deployment and retrieval problem. The tether dynamic model includes tether mass as well as in-plane and out-of-plane librations. The nonlinear feedback tension control law developed guarantees stability of the closed-loop system and is used in combination with out-of-plane thrusting during retrieval. Simulation results show the tension and the combined tension and thruster control laws perform well for deployment and retrieval, respectively, even when aerodynamic drag is considered. © 1990 by the American Institute of Aeronautics and Astronautics, Inc.
