| Summary: | The invention discloses a satellite system multidisciplinary optimization method based on multi-model fusion, and belongs to the field of spacecraft system design. The implementation method comprises the following steps: establishing a satellite system key subject analysis model, and optimizing a design variable by taking the satellite system quality as an objective function; in order to improve the solving efficiency of the system scheme optimization problem, a high-precision model and a low-precision model of the geosynchronous orbit transfer subject and the satellite platform structure subject are established, and a Co-kriging agent model is used for fusing model data with different precisions;, sequence filling sampling is carried out through multi-objective optimization with the expected improvement degree and the feasibility probability being comprehensively considered, then the design space is fully explored, and the Co-kriging agent model is updated and managed, so that a scheme which meets the task r |
