【摘要】 卫星作为无人驾驶的自主航天器,在运行寿命期间原则上是不进行维修的。一旦卫星在轨道上出现故障,卫星应该能自主进行故障诊断和重构,卫星利用自身的硬件和软件的冗余而重新稳定。研究和探讨了卫星姿态自主故障诊断和重构的方法,对这个过程进行了分析,所研究的方法计算量小,适合在线估计,精度适中。更多还原

【Abstract】 ?Satellite is a kind of autonomously controlled spacecraft without maintenance at its life span. Once it is at fault on orbit, it must have ability of selfdiagnosis and reconfiguration to regain control and stability. Hardware and software analytical redundancies can help satellite fulfill task and prolong life with fault. According to a project on satellite selfdiagnosis and reconfiguration of attitude control, several intelligent fault diagnosis methods are introduced and discussed.更多还原
