| 摘 要： | 在考虑了实际试车过程中已出现过或可能出现的故障的基础上，建立了恒庆挤压式双组元姿态控制发动机系统的稳志故障模型，并利用梯度法对该模型进行了求解。在此基础上进行了几种典型故障的仿真，分析了它们所产生的效应，识别出这些故障的模式。最后给出了用于分离和监测故障的关键参数。

| Abstract: | Considering some faults which had occurred during engine tests or would occur in thefutrue, a steady on fault models of constant pressure feed bipropellant attitude control engine systemwere derived. By means of gradient methcxl, the models were sovled. Then, several tyPical faults weresimulated, and effects of these faults were analyzed, fault modes of these faults were developed withsome selected parameters. Finally, the key parameters which are used to separate and detect differentfaults were catried out. |
