The optimal control and stability problem of reorienting a flexible spacecraft is studied for the case of simultanuous multi-axis attitude maneuver. A multi-level control strategy is proposed which tracks a predetermined optimal attitude trajectory and suppress the flexible structure deformations at the same time. The multi-level integrated control consists of a three-part control efforts. An optimal open-loop rigid-body reference trajectory is obtained from iterative procedures. An output observer feedback control is used as local control to stabilize the flexible beams. Guidance law takes the system to the desired final attitude by following the optimal trajectory. Control stability is considered on the input disturbances effects.
