摘　　要：针对传统卫星总体和控制串行设计过程低效、设计性能受限、设计方案冗余等问题,提出了一种卫星总体与姿态控制一体化优化设计方法。在轨道、结构、电源、推进等多学科耦合的传统总体设计模型基础上,将面向应用任务过程的卫星姿态控制仿真嵌入卫星多学科分析过程中,实现卫星总体方案与姿态控制的耦合精确分析和整体任务效能的综合评估,在此基础上进一步实现总体和控制的一体优化。最后,以某对地观测敏捷卫星为对象开展方法应用研究,优化结果表明所提方法获得了比传统设计方法目标函数性能更优、冗余度更低的设计方案,验证了卫星总体与姿态控制一体化优化设计方法的可行性和有效性。Aiming at the problems of iterative design inefficiency,performance limitation and the design redundancy that are caused by the independent traditional satellite overall design of control process,an integrated optimization design method of satellite overall system and the attitude control is proposed.Based on the traditional satellite multidisciplinary design optimization(MDO)model considering the orbit,structure,power and propulsion subsystems,the satellite attitude control simulation in the application mission is incorporated into the satellite multidisciplinary analysis process in order to implement an accurate analysis of coupling effects between satellite overall design and attitude control,and perform a comprehensive evaluation on the complete mission pay-back.In this way,the integrated optimization of the satellite overall system and control process can be accomplished.Finally,by taking one agile Earth observing satellite for application research,it is demonstrated the attitude control process has a great influence on the final satellite overall design solution.Besides,the integrated optimization method generates better overall design solution with better design performance and less design redundancy than the traditional MDO method,which verifies the feasibility and effectiveness of the proposed integrated optimization design method.
