Stabilization Control of the Tethered Satellite System Using Nonlinear Model Predictive Control

摘要：

　　The tethered satellite system(TSS)has some potential applications in space interferometry and remote sensing.It is advantageous to traditional free satellite formations as far as relative station-keeping is concerned.However,the dynamics of the TSS in the restricted three-body problem is extraordinary complicated,and the collinear equilibrium points are unstable.To stabilize and keep the TSS in the vicinity of the collinear libration points,the tube nonlinear model predictive control(NMPC)scheme is employed.The terms related to the influence of the tether in the dynamic model of the TSS are viewed as additive disturbances.The robustness of the controller is guaranteed by the tightened constraints of the reference trajectory.Simulation results demonstrate the effectiveness of the proposed control strategy.
