In this paper, the deployment process of linear tethered satellite formation system is studied. The scheme of phased deployment of formation system is introduced. The nominal model of the formation system is established by Lagrange’s equation, and the nominal trajectory of the tethered satellite formation system is obtained by parameter optimization based on the nominal model. Considering the influence of tether elasticity, possible slack and deformation of tether and dynamics of tether deployment control mechanism, the actual model of the formation system is built by Newton’s second law in the inertial system. Based on the actual model of the system, a robust sliding mode tracking controller is designed to track the optimal nominal trajectory. The simulation results show that the designed controller can accurately track the optimal nominal trajectory in the presence of external disturbances and has strong anti-interference ability and robustness during the deployment process of tethered satellite formation system.
