摘　　要：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.Focusing on system design problem of remote sensing satellite, optimization problem with com- prehensive objective combined by coverage width, ground sample distance and total mass was set up. Consid- ering subsystems of guidance, navigation and control （ GNC）, power, structure and thermal control （TCS） and sorting the coupled relationship between them, muhidisciplinary design optimization （MDO） model based on collaborative optimization （CO） method architecture was established and solved with penalty function meth- od. Compatible results of improved performance were obtained. The rationality of the model and the efficiency of MDO m^thod applying to satellite system design were verified. The analysis models of the subsystems and employed solving method can be referenced by engineering application of MDO method.
