Simulation-Based Performance Degradation Prognostics of Electro-Hydraulic Servo Valve
Applied Mechanics and Materials, 2014Simulation-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

New Modeling and Analysis of Three-Stage Electro-Hydraulic Servo Valve
2008 International Workshop on Modelling, Simulation and Optimization, 2008To develop higher performance three-stage electro-hydraulic servo valve, a new modeling software, AMEsim, is used to develop its non-linear model according to the construction and principles presented in this paper. The results of simulation and experimental test about an existing valve are consistent, which proves the model is right.

2009 International Conference on Intelligent Human-Machine Systems and Cybernetics, 2009
The superfluous force seriously affects the dynamic load precision of the electro-hydraulic load simulator. Aiming at this question, the work principle of the electro-hydraulic load simulator was analyzed, and the bond graph models of the flow servo valve, hydraulic cylinder and load were established.

Pressure feedback control of electro-hydraulic servo-valve for passive control of hydarulic robots
2016 13th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2016Recently, a passivity-based control has been investigated a lot because robots have been used frequently for outdoor applications. However, since conventional hydraulic robot systems which use flow-control servo-valves are not an inherent passive system, such developed passive control algorithms cannot be applied for conventional hydraulic robot ...
