Application of immune neural network for electro-hydraulic servo valve fault diagnosis
2008 International Conference on Machine Learning and Cybernetics, 2008Using the biological immunology principle unifies the neural network and the immunity algorithm to form the immunity neural network, which is applied to electro-hydraulic servo valve breakdown diagnosis. The result indicated that, the immunity neural network can identify many kinds of failures pattern recognition accurately by the smaller network scale,

An Adaptive Optimal Control Algorithm for Jet Pipe Electro-hydraulic Servo Valve
2019 Chinese Control Conference (CCC), 2019In this paper, an adaptive optimal controller design method is proposed for the jet pipe electro-hydraulic servo valve. By establishing the dynamic model of the electro-hydraulic servo valve, the state variables and control variables are selected and transformed into the solution of the optimal control problem.

Advancements and Patent Trends in Deflector Jet Tube Electro-Hydraulic Servo Valves
Recent Patents on EngineeringDeflector plate jet servo valves are mostly used in high-temperature and high-pressure situations, and are widely used in both military and industrial applications. The deflector plate servo valve does not need a winding oil supply pipe, which overcomes the vibration that may occur in the structure.
