In order to avoid the magnetic influence of satellite to the measurement information in the space detection missions, lightweight flexible booms are required to support various types of payload on their tip away from the satellite platform. While the elastic vibration of flexible booms will affect the attitude control accuracy of the satellite. Considering the complexity of appendages vibration and its effect on the satellite, an optimal input shaping(OIS) is applied to the flexible booms to suppress its loworder mode vibration, and then an adaptive disturbance rejection filter(ADRF) is designed to reject the disturbance caused by the residual vibration of booms further. Simulation results show that the proposed composite vibration control method can improve the satellite attitude control accuracy greatly.
