Abstract:

This paper puts forward a component synthesis active vibration suppression (CSVS) method for spacecraft with the large flexible appendage and analyzes its robustness to uncertainty in modeling parameters. This method can eliminate unwanted flexible vibration modes while achieves desired rigid motion; the robustness makes it practical in engineering. For a kind of spacecraft with constant amplitude reaction jet actuators, time-fuel optimal maneuver control strategies are designed using CSVS method. Simulation results validate this method.

Key words: component synthesis active vibration suppression method, optimal control, robustness, large anglemaneuver
