ADRC Design for Spacecraft with Deployable Flexible Appendages

Based on the Auto-Disturbances-Rejection Controller(ADRC),an attitude controller for a spacecraft with deployable flexible appendages is studied.In order to dynamically compensate model disturbances and uncertainties,an ADRC based controller is designed for the coupled and nonlinear model of the spacecraft during the deployment of appendages.The simulation results show that the closed loop system achieves high dynamic and static performance,and the good vibration suppression.
