Abstract

It is considered the synthesis of robust suboptimal feedback control based on minimum-time multi-revolution transfer between non-coplanar elliptical and circular orbits in the inverse square gravity field. The problem is solved using asymptotic nature and symmetries of optimal control on the unperturbed trajectory. It is shown stability of the feedback control with respect to perturbations and deviation of initial conditions. Derived suboptimal feedback control can be used for providing of spacecraft autonomy and for mission design purpose.
