Single Axis Pointing Control for Underactuated Flexible Spacecraft

The single axis pointing control for underactuated flexible spacecraft is dealt with in this paper,which is involved with not only difficult nonlinear control problems of systems with high dimension in the control theory but also spacecraft configuration and reliability in the engineering application.The proposed control method contains two steps: step 1 is to stabilize the angular velocity of the spacecraft by a new controller,and step 2 is to stabilize the single axis pointing direction of the spacecraft ...
