H-Infinity Control of Orbital Trajectories with Stochastic Models

This paper describes the formulation and numerical investigation of the robust H∞ control problem for the orbital transfer of a spacecraft between two non-coplanar orbits subject to parameter uncertainties and external disturbance. The dynamic model of relative motion illustrated by Tschauner-Hempel (T-H) equations is used to define the orbital transfer model. An illustrative example is provided to show the effectiveness of the proposed control design method.
