摘要: 分析了三轴稳定卫星姿态控制分系统与其它分系统的耦合关系,选定了姿态稳定方式和姿态控制系统硬件,建立了更为精确的计算姿态控制分系统质量和功率的分析模型,然后基于多学科设计优化协同优化算法建立了总体系统、姿态控制分系统、电源分系统和结构分系统的优化模型,最后用C语言对分析模型和优化模型编程计算.结果表明,分系统模型能与总体系统模型有效协调优化,得到更好的总体性能指标.

Abstract: The coupled relationship between the attitude control system and other subsystems of three-axis-stabilized satellite was analyzed in this paper,and then attitude control models and subsystem hardware were selected.More accurate analysis model was established to calculate subsystem mass and power,then optimization models of integrated system,attitude control subsystem,power subsystem and structure subsystem based on collaborative optimization(CO) methodology were built. Finally,the programs were compiled with Clanguage for the analysis models and optimization models.The results shows: subsystem model collaborates well with this system model to obtain better system performance.
