초록

During braking phase of lunar soft landing, the high-thrust orbit-control engine works at maximum thrust, the interference and interference-torque is in critical condition, and there is seriously attitude and orbit coupling situation. In this paper we address the problem of braking phase of lunar soft landing. An adaptive tracking control method based on traditional feedback control is designed to obtain that the control system works well under braking phase of lunar soft landing. Taking the parameters of the Apollo in the simulation model, a comparison between the traditional control method and the adaptive tracking control method is undertaken. It is shown that the proposed controller copes with braking phase and shows faster convergence speed and higher stability precision.
