Abstract

Flexible spacecrafts have been required to agile and precise attitude switching maneuver recently. For this requirement, the controller of the flexible spacecrafts is required to be robust against high-frequency unmodelled uncertainty and to have high performances of motion and vibration control. In this paper, the attitude controller of the flexible spacecrafts is designed by nonstationary frequency-shaped robust control based on the differential game theory. The weightings of the proposed controller are designed to be replaced high-frequency unmodelled uncertainty and enable the controller to suppress the spillover instability. The proposed controller generates optimal input torques to control agile and precise attitude switching maneuver of the spacecraft by the weightings of the state vector which are designed in the time domain. Several simulation results show the effectiveness of the proposed controller.
