Abstract

The invention discloses a space tethered capturing system based non-cooperative target quality identification method. After a space tethered robot system captures a space non-cooperative target, a target kinetic parameter is identified in the later capture stage and a recovery stage and then self-adaptive recovery control is completed based on the identification result. The space tethered capturing system based non-cooperative target quality identification method includes firstly, providing a parameter identification method to identify quality of the space non-cooperative target primarily in the later capture stage; secondly, providing an optimal control algorithm according to influences of different recovery control algorithms to parameter identification; and thirdly, completing self-adaptive control in space non-cooperative target recovery process on the basis of the primary parameter identification result in the later capture stage.

Description

technical field

[0001] The invention belongs to the technical field of spacecraft control, and relates to dynamic analysis and target parameter identification technology after all kinds of space capture systems with space tethers capture space non-cooperative targets, in particular to a capture system based on space tethers Non-cooperative target quality identification method. Background technique

[0002] The space tethered robot system is a new type of space robot system that can be used for space on-orbit services. It has potential application value in the fields of space on-orbit maintenance, on-orbit capture, and on-orbit assembly. The main structure of this robot system is " Space Maneuvering Platform, Space Tether, Manipulating Robot”; After successfully capturing space non-cooperative targets / space junk, the new complex is “Space Maneuvering Platform, Space Tether, Space Non-Cooperative Targets”; in order to further complete the follow-up towing For tasks such as or...
