This paper proposes a novel hybrid method aiming at the fault prognosis of bearings. A
nonlinear health indicator (HI) is first constructed using Complete Ensemble Empirical Mode …

In the field of prognostics and health management (PHM) for industrial equipment and
systems, the estimation of remaining useful life (RUL) constitutes a fundamental task. A …

Equipment will go through multiple degradation stages under complex operating conditions,
and the single-stage degradation model cannot accurately describe the degradation …

Degradation of many products in practical applications is often subject to unit-to-unit
heterogeneity. Such heterogeneity can be attributed to the heterogeneous quality of the raw …

Complex products usually fail due to competing multi-performance degradation and sudden
failure modes. The correlations between competing failure modes, including among multi …

Abstract Remaining Useful Life (RUL) prediction is of significant importance for the safe
operation of machines. However, the Health Indicators (HIs) constructed by a single feature …

Prognostics and health management (PHM) is an indispensable technology that is often
employed to ensure secure operational functionality and augment the monetary …

Accurate remaining useful life prediction of bearings in wind turbines is beneficial for safe
operation. However, conventional health indicators rarely consider monotonicity …

The stochastic nature of the multi-sensor monitored aero-engine degradation process limits
the accuracy of its remaining useful life (RUL) prediction. To address this problem, a hybrid …

An integrated and adaptive prognostic framework is proposed for hiddenly degrading
actuator in the closed-loop system. Furthermore, the dual influence of degradation progress …
