Human control intersection docking operation method

Abstract

The invention relates to a human control intersection docking operation method which is characterized in that a target which comprises a background chassis and an extended cross is arranged nearby the docking port of a target spacecraft; a television camera is arranged nearby the docking port of a tracking spacecraft; and an astronaut observes the image of the target spacecraft and the target by the television camera for carrying out the state judgment and control. According to the relative motion state of the two spacecrafts, the position and posture are adopted for the coordination control; simultaneously, the deviation of the tracking spacecraft and the target spacecraft relative to the sight line is eliminated so that when the distance is far, the target spacecraft is always at the center of the tracking spacecraft field; when the distance is near, the images of the background chassis and the extended cross of the target are coincided; under the premise, the distance between the tracking spacecraft and the target spacecraft is gradually shortened; after the tracking spacecraft and the target spacecraft berth and keep on the 3-6 meters relative position of the two docking ports, a forward engine of the tracking spacecraft is started for a certain time so as to finish the human control docking task according to the required docking speed, the transverse positional deviation and the posture deviation.

Description

technical field [0001] The invention belongs to the field of control, and relates to an operation method for space rendezvous and docking of a spacecraft when flying around and finally translationally approaching the astronauts to perform human-controlled rendezvous and docking. Background technique [0002] Space rendezvous and docking (Rendezvous and Docking, RVD) technology of spacecraft is a key technology in manned spaceflight, which can be divided into automatic control and manual control. Both the United States and the former Soviet Union achieved the rendezvous and docking of spacecraft for the first time in 1967, and then carried out a series of space rendezvous and docking activities. Although both the United States and the former Soviet Union have developed man-controlled and self-control technologies for rendezvous and docking, the United States puts more emphasis on the adoption of man-controlled technology, while the former Soviet Union puts more emphasis on th...

Problems solved by technology

In fact, manned rendezvous and docking is mostly used for control when automatic rendezvous and docking fails. At this time, the initial conditions of manned rendezvous and docking are often relatively bad, the relative attitude and relative position deviation are relatively large, and the residual relative speed will quickly make the target and target If the image exceeds the field of view of the TV camera, the docking cannot be completed using the method in "Research on the Control Method of Human-Controlled Rendezvous and Docking", and the method in this paper cannot be used to complete the human-controlled docking with the requirement of flying around.
