| 摘 要： | 研究一种以发动机部件跟踪滤波器（ＣＴＦ）为基础的解析余度技术，它将ＣＴＦ与故障检测、隔离和适应逻辑进行了有效的综合，以改进发动机数控系统的可靠性。仿真表明，本文所设计的解析余度技术，在传感器无故障时，机载模型能正确跟踪发动机的变化。当传感器发生故障时，在不损坏机载模型的情况下，又能及时、有效地进行硬、软故障的检测、隔离与适应。

| Abstract: | This paper deals with an analytical redundancy technology based on a component tracking filter (CTF),which is integrated with failure detection,isolation and accommodation logic so as to improve the reliability of the engine digital control system.Its simulation tests in complete flight envelope show that the developed analytical redundancy technique enables the engine model on board to track the component performance variations correctly in the case of no sensor failure,and to detect,isolate and accommodate failures of sensors effectively without corruption when a failure occurs. |
