摘　　要：根据火星飞行任务的特点和需求,能源系统需要实现在复杂工作模式下自主控制和调整的设计目标,以支撑火星轨道上下降与着陆、姿态调整、升降轨等复杂任务的顺利实施;突破和掌握了高效、轻量化、可自主管理的能源系统技术和能源系统自主调配技术,在系统重量资源有限的情况下,在不增加额外器件、电路或调节设备的基础上,利用判断整星工况和飞行程序综合处理当前能源工况,采用帆板实时对日和切换充电开关方式使能源达到最大利用率;并实现多项能源自主管理流程,如过压、过放、蓄电池组单体短路后的自主快速处理,无需地面干预,极大提高了能源系统供电可靠性和安全性。According to the characteristics and requirements of flight missions,the power system on Mars obiter needs to be designed to be capable for self-management and regulation in complex working modes,so that the complex missions such as descent and landing,attitude adjustment,and orbit adjustment can be realized successfully.In this paper,an efficient,lightweight,and self-managed power system is designed,and the self-management technology for the power system is presented.Without additional devices,circuits,and regulating devices,the current energy condition is processed comprehensively by judging the operating mode and flight schedule,through which the real-time orientation to the Sun,charging switch,and maximum possible utilization rate for energy can be realized.The method can realize multiple energy self-management processes,e.g.,over-voltage processing,over-discharging processing,and battery monomer short circuit processing,without ground control.This greatly improves the reliability and security of the power supply of the power system.
