Modeling and Simulation on the Guidance and Control in Deep-space Soft Landing

Fei Tan

Abstract

In this paper,the general way and the process of deep space soft landing is discussed,and the overall scheme of the guidance control in soft landing is described.With minimal fuel for performance index analysis,a kind of soft landing power decline of polynomial guidance law is obtained.With the basic requirements for safety and reliability,analysis is used to segment the gravity of the final landing turn landed method.Finally,the simulation results proved that the model is reasonable,feasible and simpler.
