WebbThe EOC PHM algorithm allows monitoring of the lubricant consumption in automatic way in order to early detect any abnormal consumptions (Demaison, 2010). This represents a major challenge because deterioration of the lubrication system has non-negligible consequences on the execution of the turbojet engine. WebbThe Prognostics Algorithm Library is a suite of algorithms implemented in the MATLAB programming language for model-based prognostics (remaining life computation). It includes algorithms for state estimation and prediction, including uncertainty propagation.
