摘要
在飞船推进系统的物理和数学模型的基础上，研究了基于模型的故障诊断方法在飞船推进系统中的应用。该方法是某飞船推进系统状态监测与故障诊断专家系统中的关键技术之一。仿真结果表明，这项技术的提出和应用使得根据系统模型对推进系统的不可预知故障进行监测和诊断成为可能。
Based on the physical and mathematical model of spacecraft propulsion system,the application of model based fault diagnosis method to the propulsion system of spacecraft was studied. This method was one of the key technologies in state detection and fault diagnosis expert systems of the propulsion system of spacecraft.The simulation result indicates that the presentation and application of this method makes model based detection and diagnosis of unexpected fault probable in the propulsion system of spacecraft
