This paper addresses the autonomous rendezvous and docking between a chaser spacecraft and a target spacecraft.An optimal control method is employed to plan the rendezvous and docking maneuver, considering various constraints, diamond painting strand en zee including force, velocity, field of view, and collision avoidance with a diamond-shaped obstacle.The optimal trajectories are derived using a symplectic algorithm, which ensures high accuracy and enhances computational efficiency.These trajectories serve as the reference for the maneuver.
A PD-based tracking control method is proposed to enable real-time feedback control.An air-bearing experimental system, encompassing state measurement, data transmission, and processing, is established to conduct ground-based tracking experiments.Furthermore, specialized simulators for the chaser and target spacecraft, equipped with ethical nutrients mega magnesium powder citrus 450g a docking mechanism, are designed.Experimental results validate both the feasibility of the reference trajectories and the effectiveness of the PD tracking control approach.
