英文摘要： This proposed project studies coordinated control methods and implementation techniques of networked satellite formation. The dynamical modelling of networked satellites is investigated by considering the features of complex distributed nonlinearities, communication constraints, internal uncertainties, external disturbance and environment constraints. To solve the coordinated control problem of networked satellite formation, three main coordinated control methods are studied. They are the optimal coordinated control method of networked satellite formation for the case of satellites with forbidden flying zones, the predictive coordinated control method of networked satellite formation for the case of satellites with communication constrains and variable network topology, and the robust coordinated control method of networked satellite formation for the case of satellites with flight attitude-orbit coupling. It discusses methods of analysing the consensus and stability of satellite formation and then derives criteria of consensus and stability of networked satellite formation using the three above coordinated control methods. Implementation techniques of networked satellite formation are developed to make those advanced coordinated control methods of the satellite formation achieve the consistent, real-time, reliable, safe and expected coordinated control performance in practical applications. A simulation test rig of networked satellite formation are designed and established to illustrate the effeteness of proposed the coordinated control methods and implementation techniques.
