Model predictive control guidance for constrained mars pinpoint landing

In order to achieve pinpoint landing under various constraints during powered descent phase of landing on Mars, model predictive control (MPC) is employed in this paper by designing a novel performance index. Its main advantage is that it can ensure the pinpoint landing with online calculation and handle constraints as well, both of which are important in practical engineering missions. Detailed derivational process is given. Simulation results show the effectiveness of the proposed guidance.
