For controlling the deployment of subsatellite, the dumbbell model of tethered satellite system (TSS) is built. The paper develops a nonlinear receding horizon feedback control rule based on the nonlinear dynamics model using an indirect Legendre psuedospectral method. The nonlinear control problem is approximated with successive linear problems obtained via a quasilinearisation around reference trajectory. The feedback gains of receding horizon control could be obtained via solving a two-point boundary value problem which may be discretized into a set of linear algebraic equations by the indirect Legendre pseudospectral method. A numerical example is included to demonstrate the strong stability and high accuracy of the feedback controller under initial perturbations.
