Adaptive robust attitude maneuver control of a flexible spacecraft with active vibration suppression

A new approach combining adaptive robust control and theory was proposed for active vibration control of a flexible spacecraft with attitude maneuver control. For effective vibration suppression in flexible appendages, the controller based on state feedback theory was used and the structural uncertainties caused by neglecting higher order modes were fully considered in the design procedure, they ensured rapid decay of vibration and the robustness of the approach. Then, the adaptive robust method was applied to develop the attitude controller of the spacecraft to reduce the influences of disturbances and uncertainties of moment of inertia. Lyapunov theory was adopted to analyze the system stability. Finally, the reasonability and effectiveness of the proposed method was testified via simulations.
