Abstract

This paper presents a real-time trajectory planning and tracking control framework for a complex-shaped chaser to approach a rotating target with complex shapes. The framework is divided into two layers: trajectory planning and tracking control. Firstly, considering the complex shapes and relative attitude constraints of the target and chaser, a real-time critical safety curve (RT-CSC) is proposed as a collision avoidance constraint combined with the rotational motion of the target. Secondly, the multi-constraint improved disturbed fluid method (MCIDFM) is proposed. The flow field velocity is designed by considering proximity time optimization under boundary and chaser thruster performance constraints. Trajectory planning is achieved by making the flow field bypass the non-convex keep-out zone formed by the RT-CSC. Then, the tracking control is implemented using a model predictive control method and the closed-loop asymptotic stability is demonstrated. Simulation results demonstrate the proposed methods’ smoothness, safety, and strong approach capabilities. Rapidity and robustness are also reflected in simulation analysis.

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
