摘　　要：针对故障特征数据模拟生成算法与航天器的原理、模型关联度高,航天器状态描述模型不成熟、难以应用于工程实践的现状,根据反映航天器在轨故障的遥测数据表现形式和变化时间长短,将航天器故障进行分类。从遥测数据变化的角度,针对每类故障遥测数据的变化特点,研究了符合每类故障数据变化规律的故障特征数据生成算法及基于WEB服务的故障特征数据生成原型系统实现方式。生成的故障特征数据在故障检测、诊断与预警等方面得到成功应用,使航天器对象、状态演化规则和测控信息产生等故障输入数据更接近真实的动态特征。Spacecraft fault properties data generation algorithm is highly correlated with the principles or model of a spacecraft and spacecraft state description model is not mature enough for engineering applications. To solve these problems, spacecraft faults are first classified into pulse type faults, step type faults and gradual type faults based on their duration and expression of telemetry data refleeting in-orbit faults. Taking into account the variation of telemetry data and the characteristics of each type of fault telemetry data, the algorithm that generates fault properties data according to fault data evolution rule is studied. The resizable array of fault properties data generation system based on WEB service is studied as well. The fault properties data of the generation algorithm is closer to actual dynamic characteristics when it is used in fault detection and diagnosis.
