Abstract

The optical loads on high-resolution satellites are very sensitive to vibration. Therefore, it is crucial to meet the pointing accuracy and micro-vibration suppression for the optical loads. In this work, a parallel platform with nine legs is designed for integrated micro-vibration and pointing control. The legs include six legs for micro-vibration and three legs for pointing control. Combining the decoupling of micro-vibration and attitude motion, a joint control model is built in Matlab/Simulink. The simulation result shows that the new platform can achieve good performance in both micro-vibration suppression and precision pointing control.
