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.
