A novel method of vibration suppression for multi-modal flexible spacecraft
In order to reduce the vibration of the flexible attachments,a combined control strategy based on input shaping and a PD adaptive feedback control is proposed.The multi-modal flexible attachments will create the vibration in the attitude maneuvers,therefore the spacecraft with imaging function cannot insure the image quality.In allusion to this problem,the multi-modal input shaper is designed to improve stability which based on the vibration frequency and damping ratio of the entire closed-loop system.Considering the control system of attitude dynamics structure and the uncertainty parameter,a PD adaptive feedback control is used.From the simulation results it can be seen that the proposed control strategy can quickly reduce the flexible attachments vibration and improve the performance of closed-loop system.
