An Improved sliding-backstepping control law for large flexible satellite attitude maneuver

摘要：

A so called sliding-backstepping controller for attitude maneuver in some large flexible satellite is put forward. Further, combined with theory of Extended State Observer (ESO), the controller has been improved to estimate and compensate the uncertainties. After the stability analysis, simulation was carried out in particular using Single Gimbal Control Moment Gyros (SGCMGs) as the momentum actuator and considering the first ten elastic modes. The results achieve the mission requirements and conform to aforementioned theoretical analysis. Furthermore, the improved controller has significant advantages in pointing accuracy and flexible suppression.
