Simulation-Based Performance Degradation Prognostics of Electro-Hydraulic Servo Valve

Abstract:

Simulation-based performance degradation prognostics should firstly obtain the judgment criterion to predict degradation failure, how systems or its components degenerate, and then how to display effect of degradation process on performance. In this paper, we presented a model-based performance degradation prognostic method to address this problem. For Electro-Hydraulic servo valve case, it has strict demands on performance. Degradation of the valve is propagated forward in time and influence on performance output. The proposed degradation prognostics method is illustrated through performing comprehensive simulation experiments.
