Abstract
Due to the increase in popularity of satellite constellations, some altitudes in LEO have experienced a large increase in number of satellites. This is a trend expected to continue in the future, which could potentially lead to an increased risk of collision between satellites. Collision avoidance is therefore paramount to maintain normal operations and to prevent runaway growth of space debris in LEO. To that end, this thesis develops state-space LQR and tube MPC controllers for LEO satellites operating in near-circular orbits with low-thrust engines. This is done using a linearized model of the dynamics under the Earth gravitational potential and the atmospheric drag.
