摘要
介绍航空发动机试验过程中,常见的传感器卡死、传感器恒增益变化和传感器恒偏差失效等故障,以及当传感器数据出现异常时,对传感器进行故障诊断的理论方法。对传感器故障诊断有待解决的问题和发展方向做了一定探讨。
This paper introduces mainly several common sensor failure in the aero-engine experimental process,sensor stuck,constant changes in sensor gain and constant deviation of sensor.The basic principles and theories used to diagnose sensor faults are proposed when the obtained data is abnormal.Finally,there are some discussion of the problem to be solved on the sensor fault diagnosis and the research direction to be developed.
