LPV Robust Filter Based Fault Diagnosis Method for Aeroengine Control System
摘要
As the most typical component of an aeroengine control system, the sensor operates under high temperature, high pressure and high speed for a long period of time. It is exposed to a high rate of faults occurring. An analysis and design study of LPV robust filter-based fault diagnosis method for aeroengine control system is conducted based on the idea of multi-sensor fusion estimation under unknown disturbance and model uncertainty. Simulation experiments verify the effectiveness of the filter is applied to sensor fault diagnosis of the aeroengine control system.
