Stability and nonlinear oscillations at a flexible satellite respinup by weak internal torques

Nonlinear processes are considered at a satellite respinup for combining the body angular momentum on its maximum inertia axis with direction of any given unit into inertial reference frame. Moreover the weak internal torques are applied which are formed by gyromoment cluster with bounded resources. For realization of such respinup we synthesized nonlinear control law which ensures asymptotic stability of given satellite motion. Efficiency of suggested approach is confirmed by results of computer imitation.
