Research of non-servo valve electro-hydraulic servo system

Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011
A new non-servo valve electro-hydraulic servo system was researched. To control load, the system uses bidirectional fixed displacement hydraulic pump that is driven by AC PMSM directly drives servo-hydraulic cylinder. The hydraulic actuating unit was designed base on one design parameter and performance target.

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

Applied Mechanics and Materials, 2014
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
