Magnetic control of tethered cube-satellite stabilized by rotating

Active magnetic control have been used to develop the rotating stabilization of tethered nano-satellites. It uses magnetic control to stabilize the orbit position by controlling angular velocity of rotating TCS. The system uses Earth´s magnetic field as energy source to interact with a long conductive tether and consecutively reach the rotational stability on Low Earth Orbit (LEO). The mathematical model and control design describing orbiting system for two connected cube-satellites with a 1-km-length tether have been studied. The adaptive version of sliding mode control was used to control the system in presence of unmodelled dynamics and perturbations. The performance of this system has been investigated via simulation.
