Abstract:

In the field of space science and exploration, the Moon and Mars hold significant importance as destinations. When it comes to a planetary soft landing mission, a crucial requirement is for the space exploration vehicle to touch down on the surface with no relative velocities. Achieving this challenging feat is made possible by employing a fixed thrust motor and applying optimal control theory. The primary aim of this research is to develop a power descent guidance algorithm, both in open and closed-loop configurations, ensuring efficient guidance for soft landings and validating its effectiveness. As an initial step, Using predetermined performance specifications, a three-dimensional open-loop analysis is explored. Subsequently, the validity of three-dimensional open-loop guidance is verified. To overcome the limitations that may be associated with external disturbances, plant uncertainty and so forth in open-loop guidance, a closed-loop guidance algorithm using the Linear Quadratic Regulator (LQR) approach is employed. The closed-loop guidance using LQR is analyzed. MATLAB simulations are conducted to verify the obtained results.

I. Introduction

Space exploration has seen numerous accomplished missions since the 1950s. These missions aim to explore various celestial bodies within our solar system, enabling scientists to study their nature and conduct further research in the search for extraterrestrial life. Each mission shares a crucial goal: achieving a soft landing of the spacecraft. A soft landing refers to the careful descent of the vehicle onto the surface, ensuring the spacecraft remains intact and undamaged.
