The Electro-Dynamic Tether (EDT) System uses the Lorentz force as a thruster generated by the interference between Earth's Magnetic filed and the electric current along the tether. The EDT system is expected as a new space technology that will be useful in many types of space applications such as reboosting of the international space station, deorbiting of dysfunction satellites and many kinds of scientific mission. The motion of the EDT system in an elliptic orbit consists of libration and rotation and it is known to be chaotic. To stabilize the chaotic motion, several control schemes have been proposed. Especially control schemes which use the periodic solution of the EDT system have been studied recently. In this research, Delayed Feedback Control is used to stabilize the chaotic motion of the system to the periodic solution and the stability of the closed-loop system of Delayed Feedback Control is analyzed by Floquet's theory.
