Model Predictive Control Guidance for Constrained Mars Pinpoint Landing

Abstract

Abstract:This paper investigated an approach to trace a fuel optimal trajectory for Mars pinpoint landing mission with a variety of geometrical constraints. A model predictive control(MPC)approach is designed to minimize the performance index while at the same time keeping the constraints. With the proposed method,the spacecraft can achieve pinpoint landing. To validate the effectiveness of the proposed MPC approach,simulation results are included for illustration.
