Attitude stabilization of spacecraft with two moving-mass via interconnection and damping assignment

This paper deals with attitude control of spacecraft with two moving-mass. Two mass particles are constrained to move in different circular track fixed within the spacecraft, respectively. The dynamical model of the spacecraft is presented in a reduced dimensional Hamiltonian form. The Hamiltonian model is noncanonical and underactuated. We consider the application of interconnection and damping assignment to the problem of attitude stabilization of the underactuated spacecraft with two moving-mass.
