Abstract
Remaining useful life (RUL) estimation is critical to facilities under poor working conditions to prevent major safety accidents. In this article, we propose a data-driven scheme adopting a gated neural network, similarity-metric curve matching technique and the greed matching strategy to predict the RUL of facilities. The gated neural network transforms the multi-dimensional sensor readings to low-dimensional embedding, which are used to describe health degradation followed by linear regression to get the health index (HI). The online step is to match the test HI curves to the trained HI curves using the similarity-metric HI curve matching technique, which calculates the best match between the test HI curve and the training HI curves, and the greed matching strategy. The greed strategy contributes to limiting the scope of searching the time tag, which determines whether the two curves (one test HI curve and one training HI curve) match well or not by the similarity-metric HI curve matching technique. The proposed approach was test on the turbofan engine dataset #1 and comparison results show good performance compared to other existing approaches.
