摘要

This paper presents the formulation and implements the attitude and vibration control for a satellite carrying two solar panels modeled by FEM, The PID control technique has been used and applied to the nonlinear system of equations. Analysis of the results confirmed that the attitude control excites the solar panels' vibration modes and vice-versa. Also, the piezoelectric vibration control shows significant performance improvement when compared to structural damping and contributions of the attitude control to the vibration damping. The control structure interaction for this study did not affect significantly the attitude (when there are perturbations on The flexible modes) and the flexible modes, when the attitude control is in operation.
