Titre : Nonlinear attitude control of flexible spacecraft with scissored pairs of control moment gyros Type de document : texte imprimé Auteurs : Jixiang Fan, Auteur ; Zhou, Di, Auteur Année de publication : 2012 Article en page(s) : 05 p. Note générale : Dynamic systems Langues : Anglais (eng) Mots-clés : Flexible  spacecraft  Nonlinear  controller  Three-axis  large-angle  attitude  maneuvers  Vibration  suppression  Pseudo-inverse  steering  law  Lyapunov  theory Résumé : Dynamic equations describing the attitude motion of flexible spacecraft with scissored pairs of control moment gyroscopes are established. A nonlinear controller is designed to drive the flexible spacecraft to implement three-axis large-angle attitude maneuvers with the vibration suppression. Singularity analysis for three orthogonally mounted scissored pairs of control moment gyros shows that there exists no internal singularity in this configuration. A new pseudo-inverse steering law is designed based on the synchronization of gimbal angles of the twin gyros in each pair. To improve the synchronization performance, an adaptive nonlinear feedback controller is designed for each pairs of control moment gyros by using the stability theory of Lyapunov. Simulation results are provided to show the validity of the controllers and the steering law.
