Abstract
AbstractAs a case of asymmetric satellite with flexible appendages, it is known that there exists coupled vibration between rotational motion and translational motion. Therefore, when an asymmetric satellite rotates, elastic vibration excited by control input of rotational motion may be transmitted to translational motion. Reversely, suppression of such an excited vibration of translational motion would help realizing attitude maneuver with little vibration.From the reason mentioned above, in this paper, we propose translational motion control system using proof-mass actuators and co-located accelerometers for asymmetric satellite. Then, translational motion control law with consideration of actuator control loop was studied. The proposed translational motion control system was verified through numerical simulations.
