Abstract

To solve the problems of low accuracy and poor robustness of the existing aeroengine multi fault diagnosis schemes. In this paper, the actuator fault with high fault probability in aeroengine control system is taken as the research object. Considering the parameter uncertainty and the existence of multiple multiplicative faults, the state space equation of the engine is established, and the adaptive robust diagnosis method is constructed. The adaptive sliding mode observer is designed to detect the fault, and the adaptive observer is designed to estimate the multiplicative fault, System status tracking is realized. Simulation results show that the proposed method is robust and adaptive while ensuring the accuracy of fault diagnosis and estimation.
