Attitude Tracking and Synchronization for Spacecraft
Jianhua Li · Radio Engineering · 2014
To investigate the attitude tracking and synchronization of formation-flying satellites with the occurrence of various perturbations,information-communicating topological graphs are introduced to realize information communication. In this way,their own control of the satellites in the formation can be determined in accordance with their preset attitudes,their own attitudes and the attitudes of other communication satellites in the formation. Two control laws for the satellite attitude tracking and synchronization are proposed under the situation of sinusoidal disturbances with different amplitudes and frequencies,i. e.,the one based on backoff algorithm and internal modeling principles,and the other on quaternion auxiliary system. The global asymptotic stability of the system is proved by using Lyapunov methods. Simulation results are provided to show the correctness.
