| Abstract: | Chaotic planar libration and its control of a magnetic rigid spacecraft with internal damping in an elliptic orbit near the equatorial plane of the earth are investigated. The Melnikov analysis is carried out to present the condition of existing transversally heteroclinic points. The dynamical behaviors are numerically identified by numerical means such as Poincare map and Lyapunov exponents. The input output feedback linearization control and its local linearization are respectively applied to control chaotic attitude motions to the given fixed point. |
