Abstract:

Space net capturing is a novel technique for spacecraft capturing. In this paper, the disturbance imposed on the mother satellite, and the induced attitude control problem of the satellite, are investigated. Attention is focused on the dynamic process of mass ejection. The main factors affecting the performance of the net are analyzed and the model of the disturbance torque is developed. A sliding mode controller is developed to stabilize the attitude of the satellite and rigid mathematical proof is provided. Numerical simulation is conducted which demonstrates the effectiveness of the proposed algorithm.
