针对既定目标,采用卫星系统进行协同观测可以最大化卫星系统的整体效能,如何对卫星系统的轨道或载荷参数设计是一个设计空间大、设计变量多的优化问题。对此,采用基于代理模型的仿真优化,通过改进广义模式搜索算法在设计空间中搜索最优解,并以此为核心设计开发卫星系统仿真优化平台。该平台集成问题建模、仿真优化和结果评估显示,为用户提供设计和改进卫星系统方案的方法和依据。采用该平台对卫星系统设计实例进行优化,通过对比发现,平台的优化结果稳定性和优化效率优于STK-Analyzer。
For a given goal, using satellite system for collaborative observation can maximize the overall performance of the satellite system. How to design orbit or load parameters for a satellite system is an optimization problem with large design space and large design variables. In this regard, the simulation optimization based on the agent model is used to search for the optimal solution in the design space by improving the generalized pattern search algorithm, and as a core, the satellite system simulation optimization platform is designed and developed. The platform integration modeling, simulation optimization and result evaluation show that it provides users with the methods and basis for designing and improving the satellite system solutions. The platform is used to optimize the design examples of satellite systems. By comparison, it is found that the optimization results of the platform are superior to STK-Analyzer in terms of stability and optimization efficiency.
