doi:10.3969/j.issn.1001-506X.2020.07.28

Abstract

Abstract:

In order to solve the problems of high dimension and large scale of multi-sensors monitoring data and insufficient consideration of time series information in the remaining useful life (RUL) prediction of the aircraft engine, a RUL prediction method based on the long short-term memory (LSTM) network and deep belief network (DBN) is proposed. Firstly, the time series of a single sensor is predicted by using the LSTM network. Secondly, the prediction results are integrated into the DBN to extract the health indicator. Thirdly, the RUL prediction results are obtained by combining the health indicator prediction curve and the failure threshold. Finally, to validate the feasibility and the effectiveness of the proposed method, an experiment is carried out on the commercial modular aero-propulsion system simulation data set and the prediction results are compared with the existing methods.

Key words: long short-term memory (LSTM) network, deep belief network (DBN), health indicator, remaining useful life (RUL) prediction
