Fault diagnosis of electro-hydraulic servo valve based on neural network

2011 International Conference on Electric Information and Control Engineering, 2011
Electro-hydraulic servo valve is a kind of equipment that always leads to some faults in the automatic gauge control system of the strip rolling mill. In order to diagnose faults of electro-hydraulic servo valves better, a three layers BP neural network was designed based on collection and analysis on the characteristic information of some their faults

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), 2016
Recently, 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 ...
