Performance Evaluation Method of Remaining Useful Life Prediction Based on Pseudo Life

摘要：

Based on analyzing existing metrics for prediction performance evaluation, features and defects of these metrics are summarized. A new performance evaluation method of remaining useful life (RUL) prediction is proposed, which can be used before the end-of-life of a product. The evaluation principle of this method is described in detail. A new evaluation metric named fluctuation coefficient of pseudo life is also proposed on the basis of related definitions. This new metric can be used in integrated evaluation for a prediction system. The detailed evaluation flow of this method is given. Finally, a case of RUL prediction for aircraft battery is given, and quantitative performance evaluation of RUL prediction is made by calculating this evaluation metric. The evaluation results show this new method is feasible and effective.
