Attitude stabilization of a rigid spacecraft using two momentum wheel actuators [PDF]
It is well known that three momentum wheel actuators can be used to control the attitude of a rigid spacecraft and that arbitrary reorientation maneuvers of the spacecraft can be accomplished using smooth feedback. If failure of one of the momentum wheel

Torque equilibrium attitude control for Skylab reentry [PDF]
All the available torque equilibrium attitudes (most were useless from the standpoint of lack of electrical power) and the equilibrium seeking method are presented, as well as the actual successful application during the 3 weeks prior to Skylab ...

Description and simulation of an integrated power and attitude control system concept for space-vehicle application [PDF]
An Integrated Power and Attitude Control System (IPACS) concept with potential application to a broad class of space missions is discussed. A description is given of the basic concept of combining the onboard energy storage and attitude control functions

, 2010 A model reference adaptive control methodology is presented by using hyperstability theory. The main contribution of this work effort lies in the use of decentralized minimal controller synthesis algorithm to guarantee the overall asymptotic stability and to highly enhance the robustness of the attitude control system of flexible spacecraft against ...
