针对遥感卫星的总体参数设计问题,建立以卫星覆盖幅宽、地面分辨率和总重综合的指标为目标的优化问题,考虑卫星的控制(GNC,Guidance,Navigation and Control)、电源、结构和热控(TCS,Thermal Control System)分系统的分析模型并整理其中的耦合关系,以协同优化(CO,Collaborative Optimization)方法为框架建立多学科设计优化(MDO,Multidiscipli-nary Design Optimization)模型并用罚函数法求解,获得了协同一致且性能提升的结果.验证了所建模型的合理性和MDO方法应用于卫星总体参数设计优化的有效性.各分系统的模型及求解方法可为MDO方法的工程化应用研究提供参考.
In order to solve the problem of the overall parameter design of remote sensing satellites, an optimization problem aiming at the combination of satellite coverage width, ground resolution and total weight is established. Consideration of satellite control (GNC, Guidance, Navigation and Control), power supply, structure and heat (TCS) and analyze the coupling relationship between the two systems. Based on the Collaborative Optimization (CO) method, a multidisciplinary design optimization (MDO) model is established and a penalty function Method to obtain the results of synergetic and performance improvement.It validates the rationality of the model and the effectiveness of MDO method in satellite parameter optimization.The model and solution method of each subsystem can be used to engineer the MDO method Applied research for reference.
