| Abstract: | 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. |
