Automatic Posture Alignment Method of Spacecraft in Docking Process of Solar Wing

Solar wing provides energy for the whole spacecraft and the docking quality of solar wing directly influences whether solar wing can be smoothly started and put into normal operation after launching of spacecraft. First of all, traditional posture alignment method of spacecraft in docking process of solar wing is analyzed so as to point out existing disadvantages; secondly, detailed description is provided for system composition, principles for posture alignment and technological process of automatic posture alignment method of spacecraft so as to clarify coordinate transformation relationship in process of posture alignment; thirdly, error in posture alignment method is analyzed to formulate corresponding control methods; in the end, verification is carried out for automatic posture alignment method for docking engineering test of solar wing and the results show that: the method for automatic posture alignment of spacecraft is feasible and the posture of spacecraft can meet docking requirements of solar wing after 1 to 2 times of adjustment. The method can provide reference for docking process of similar large components.
