Recent advances in dynamical modeling and attitude control of flexible spacecraft

This work is focused on some recent advances on spacecraft dynamical modeling and attitude control. First, the problem of correctly linearizing the elastic behavior of spinning flexible spacecraft is discussed, and an example is presented that addresses this topic from both the analytical and the numerical point of view. Then, attitude control is considered and a new feedback law for single axis alignment is presented, together with the inclusion of accurate modeling of the actuation dynamics. Moreover, numerical simulations for the reorientation of a flexible multibody spacecraft are provided.
