摘要：
Considering maneuvering spacecraft with high flexible appendages, the translational and rotational coupling vibration modes between flexible structures and center rigid body are excited by the simultaneous attitude and orbit maneuvering. Aimed at higher stability of attitude and orbit control of spacecraft, an integrated modified positive position feedback (MPPF) controller is proposed to suppress the vibration of flexible structure. First, dynamic model is established with translational and rotational coupling effects considered, and coupling mode parameters are calculated. Then, an integrated controller was designed to suppress the translational and rotational coupling vibration modes based on MPPF. Controller parameters were optimized through M-norm optimization method. Active vibration control system is constructed using piezoelectric smart material. The simulation results show that the proposed controller is efficient on vibration suppression of the flexible structures and the stability of attitude and orbit control of maneuvering spacecraft is improved. © 2018, Editorial Board of JBUAA.
