模块化可重构卫星在轨自重构的分层规划

The modular reconfigurable satellite has the characteristics of flexible organization, convenient operation and strong adaptability, which can effectively reduce the satellite development and launch cost, improve the satellite's response speed to emergency missions, and extend the life of the satellite. Reconstruction planning problem solves the specific moving mode of the module, which is one of the core problems that need to be solved to realize self-reconfiguration. For the isomorphic rotating cubic structure, the discrete motion model is given and the motion space solving algorithm is derived. In order to reduce the uncertainty and complexity of the reconstruction planning problem, the hierarchical planning strategy is adopted to decompose the planning task into the upper layer planning of the intermediate design and the lower layer planning to obtain the intermediate configuration moving solution. The Kuhn-Munkres algorithm is used to realize the reconstruction planning algorithm of the upper layer planning, which makes the intermediate configuration have a small structural span, which is especially suitable for solving the reconstruction planning problem in the orbit self-reconstruction. The simulation results show the feasibility and effectiveness of the proposed planning strategy and the designed planning algorithm.
