Abstract: To study the vibration control of satellite with flexible solar panels under disturbance, the disposable micro impulse thruster array（DMITA） is propose to settle on the solar panels as actuators for active vibration control. The DMITA is characterized by small size, low cost and low energy consumption. The application scheme of disposable micro impulse thruster active vibration control system（DMITAVCS） is introduced and the attitude dynamic equations of flexible satellite with DMITAVCS is derived by hybrid coordinate method. The optimal energy principle for settlement location of DMITA is also analyzed. Numerical simulations demonstrate that the DMITAVCS can suppress the vibration of flexible satellite in a short time, which benefits from the long arm of force produced by the DMITA settled on the solar panels.
