| Abstract: | The improved structural filter combined with Positive Position Feedback(PPF) controller is investigated for high precision attitude control of flexible spacecraft which consists of rigid central body and flexible appendages. PPF controller is adopted for high frequency vibration suppression, while the improved structural filter is used for suppression of low frequency vibration. After introducing PPF controller, the vibration frequencies are changed. In view of the frequency uncertainties, an improved structural filter is designed, and the stability study for the centralized control system is conducted. The simulation results show that the performance of spacecraft control system is improved, and the control inputs remain unchanged. |
