Orbit control and hovering in asteroid dynamical enviroments using Higher Order Sliding Control theory

Abstract

Close proximity operations around small bodies in general and asteroids in particular are extremely challenging due to their uncertain dynamical environment. In this paper, we apply Higher Order Sliding Control (HOSC) theory to devise a class of 2-sliding homogeneous controllers that are suitable for autonomous orbit control and hovering in highly uncertain dynamical environments typically founds around asteroids. The class of controllers that can be constructed using the HOSC theory are shown to be globally finite-time stable against perturbations with known upper bound. The properties of the proposed 2-sliding controller and its contractive properties are both demonstrated both via a Lyapunov-based theoretical analysis and via simulation of closed-loop trajectories. The latter involves simulating the motion of the controlled spacecraft in the dynamical environment around Eros to demonstrate the effectiveness of the control algorithm for autonomous hovering and other close-proximity operations around asteroids.
