Modeling and Slew-Maneuver Control of a Flexible Spacecraft
<p>Slew-maneuver control problem is studied for a flexible spacecraft consisting of a rigid main body to which a long flexible appendage is attached. Nonlinear dynamical system models are developed using both distributed parameter modeling and discrete parameter modeling; these models are shown to …

Output feedback rotational maneuvers and vibration damping of Nasa Scole system by inversion theory
We treat the question of large rotational maneuver and vibration stabilization of NASA Spacecraft Control Laboratory Experiment System (SCOLE). The mathematical model of SCOLE System includes the dynamical equations for rigid body slew maneuver and three dimensional vibration of the rigid space …

Optimal Slewing of a Constrained Telescope Using Seventh Order Polynomial Input Torques
… of motion. This paper presents a method for slewing a telescope in space with a gimbaled sensor attached to a nominally non-rotating spacecraft using two seventh order polynomial input functions to characterize torques. To accomplish this task, picking the optimal coefficients of the seventh …

Testing the attitude determination and control of a CubeSat with hardware-in-the-loop
… from the nominal LVLH attitude after its slew maneuver, before payload spin-up. During its science operation mode, the tests showed a pointing deviation from nominal attitude of about 2.2 degrees (3[sigma]). The details of the constraints and limitations of the test environment and their …
