Model predictive control for spacecraft rendezvous and docking with a rotating/tumbling platform and for debris avoidance

Abstract

A Model Predictive Control (MPC) approach is developed for spacecraft rendezvous and docking to a rotating/ tumbling platform and for debris avoidance maneuvers. With this approach, the constraints on thrust, approach velocity and spacecraft positioning within the Line-of-Sight cone from the docking port are systematically treated. The trajectories are simulated and time-to-dock and fuel consumption are evaluated as cost function parameters are varied. Debris avoidance maneuvers are considered, with the debris in the spacecraft rendezvous path.
