Electro-hydraulic Servo Valve Systems

چکیده
Hydraulic systems driven by servo valves provide highly accurate control over enormous forces. A servo valve system consists of a transducer, a servo amplifier, a servo valve, and an actuator with a connected load. It is a closed-loop system used for the precise control of the output (load) parameter, such as position, velocity, or force, in response to a command signal. The output is converted into an equivalent electrical signal by the transducer. This feedback signal is compared to a command signal (representing the required output) to generate an error signal. The error signal is amplified by the amplifier.

Analysis of Performance Effect Factors of Three-Stage Electro-Hydraulic Servo Valve
TAbstract T— A new modeling software, AMEsim is put forward in this paper to develop a nonlinear model for a higher performance three stage electro-hydraulic servo valve. The simulation results and experimental results on existing valve are consistent, which proves that the developed model is right. The analysis of the model shows that pilot valve bandwidth mainly affects the bandwidth of three...
متن کاملNonlinear Adaptive Robust Control Of Electro-Hydraulic Servo Systems With Discontinuous Projections
This paper studies the high performance robust mo tion control of electro-hydraulic servo-systems. The dynamics of hydraulic systems are highly nonlinear and the system may be subjected to non-smooth and discontinuous nonlinearities due to directional change of valve opening, friction, and valve overlap. Aside from the nonlinear nature of hydraulic dynamics, hydraulic servo systems also have la...
متن کاملThe Velocity Control of the Electro-hydraulic Servo System
Abstract In general two basic methods are used for controlling the velocity of a hydraulic cylinder. First by an axial variable-displacement pump for controls flow to the cylinder. This configuration is commonly known as a hydrostatic transmission. Second by proportional valve powered by a constant-pressure source, such as a pressure compensated pump, drives the hydraulic cylinder. In this stud...
