| Abstract: | Chaos and its control in the planar libration of a magnetic rigid spacecraft with internal damping in an elliptic orbit are investigated.The dynamical model of the problem is established.The Melnikov analysis is carried out to obtain the existence condition of transverse heteroclinic cycle.The motions are numerically identified by means of Poincare map and Lyapunov exponents.The input_output feedback linearization method and its modified version are respectively applied to control chaotic attitude motions to the given attitude rest and the periodic motion. |
