大型模块化航天器可通过在轨模块更换技术替换故障及过时模块，延长航天器寿命。模块更换后，航天器质量特性发生变化，而高精度轨道和姿态控制要求准确的航天器质量特性参数作为已知输入。针对此问题，提出了基于参数解耦和分散协同控制技术的在轨辨识方法。所提方法能够快速辨识出具备多套姿态控制模块的大型复合航天器的质量特性参数，辨识精度高，满足实时在轨辨识要求。

The fault or obsolete module of large modular spacecraft can be replaced by using On-Orbit module replacement technology to extend its lifetime,but the mass-property of the spacecraft is changed by module replacement. High-accuracy orbit and attitude control requires accurate spacecraft mass-property parameters to be the known output. The identification method based on decouple parameters and decentralized cooperative control technology is proposed to solve the problem. The method can rapidly identify the mass-property parameter of the large-scale spacecraft which has multi-attitude control modules. Its identi-fication accuracy is high enough to meet the requirement of real-time identification.
