| 摘要: |
| 从系统功能设计过程出发，在分析反馈系统工作原理及其功能角色模型构造特点的基础上，认为反馈信号在输入端可等效为正、负、零三种误差信号。以此为基础，提出了反馈系统基于该理论的故障传播分析方法和技术。最后以飞机发动机燃料计量系统为例，阐述该方法在反馈系统中应用的可行性。经案例分析表明，该方法可以比较有效地解决一类带反馈环的故障分析问题，大大提高了功能角色模型的应用范围。 |

| Abstract: |
| Based on the related knowledge of the functional disassemble in the engneering design. The feedback signal is thought to be classed as positive, zero, negative signal at the port of input by analyszing the working principles and its functional role model construction of feedback system. Then, the technology of the fault transmit analysis about feedback is put forth. The process of the fault analysis is illustrated by the fuel-metering system of the jet plane engine. The research results show this method can resolve a type of fault analysis of the feedback system effectively, and the range of applications of the functional role model is extended along with it. |
