This study proposes an active vibration control method to attenuate vibrations of large flexible structures during on-orbit missions.The dynamics of the structures is modeled using Distributed Transfer Function Method (DTFM).Time domain analysis and frequency domain analysis are carried out to study the static and dynamic behaviors of the structures.The locations of the actuators are optimized using genetic algorithm and quadratic programming, the object function of which is the weighted presentation of the control voltage and the number of actuators.
