Input Limited Spacecraft Formation Flight Attitude Cooperative Control

In recent years, with the rapid developed space technology, more and more experts and scholars put their e?orts on researching formation ?ying issues of space missions. This thesis studies multiple spacecraft and conducts the thorough research on attitude coordinated control problem of formation ?ying. And the contents are as the following:This thesis introduces spacecraft attitude dynamic and kinetic models, basic concept of graph theory, and the features of the relative matrices. Meanwhile, the de?nition and theory of stability of nonlinear system are discussed.The attitude coordinated control problem of spacecraft formation ?ying is studied. Considering that problem with input constraint, attitude coordinated control algorithm is presented to make the attitudes of spacecraft in formation to achieve synchronization. Further, a control protocol of that problem with actuator failure is studied and the asymptotic stability of the closed-loop system is proved. Moreover, numerical simulation is given to verify the e?ectiveness of proposed control algorithms.Output feedback attitude control problem of spacecraft formation is studied. In the directed topology, an output feedback attitude coordinated control law of spacecraft formation is given. Attitude tacking control problem of spacecraft formation is considered, an output feedback tacking control algorithm is given to guarantee the attitude synchronization and tracking of spacecraft. And numerical simulation results verify the e?ectiveness of the proposed control algorithms.
