Abstract

The development of a switching surface constraint based on the D’Amico relative orbital elements (ROE) is presented in this paper. Relative orbital elements give a more intuitive understanding of how the relative motion of a cluster of satellites changes with time and allows the control algorithm to take advantage of the natural dynamic motion. This work models each vehicle using a model predictive control (MPC) approach, based on the Hill-Clohessey-Whiltshire (HCW) equations, to plan maneuvers which are simulated using a high-fidelity motion model. An ROE based convex polytope switching surface is added to the MPC formulation to force the states to stay within the prescribed volume. The ∆V usage of a given scenario using the ROE switching surface is compared to a cube and sphere switching surface.
