摘　　要：为满足精细化建模和故障仿真验证需求,根据摆动式红外地球敏感器的工作原理,对其进行功能模块划分,分析各模块主要故障模式,建立基于物理机理的故障数学模型,编写仿真程序进行正常和故障仿真验证。结果表明所建立的地球敏感器精细化故障模型,能够正确计算姿态角,反映内部各模块间信息传递关系,还能有效地模拟各种故障模式,可以应用于卫星控制系统仿真测试和故障诊断等方面。In order to meet the requirements of refined modeling and fault simulation, function modules of swing infrared earth sensor（IRES） was identified according to its working principle, main fault modes of each module was analyzed, mathematical fault model based on physical mechanism was designed, and a program for normal and fault simulation was written. The refined fault model can calculate attitude angles exactly, reflect signal relationship between inside modules, and simulate various fault modes effectively. The model can be used in simulating, testing and fault diagnosis and so on.
