Proportional and Servo Valve Technology
8 • Fluid Power Journal March/April 2003 The ability to achieve automated stepless control of pressure and flow rate in fluid power systems has undergone major development in the past twenty-five years. Electrohydraulic servo valves were invented in the late 1930s as a high tech, though high cost, solution to motion control needs. The mid-1980s saw the practical introduction of proportional val...

متن کاملElectro-hydraulic Servo Valve Systems
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...
متن کاملDesign Servo System Type and Positioning of Pole Observer Full Rank a Piezoelectric Servo Valve without Integrator
In this paper, the method of modern control approach for the design of controller and observer is used. Other functions such as neural controllers - or fuzzy sliding mode control can be found in this work and the results are compared. First, a dynamic model of the servo valve is intended for the governing equations in state-space form expression are obtained. Due to the system integrator is exp...
متن کاملDynamic Redesign of a Flow Control Servo-valve using a Pressure Control Pilot
In this paper, the dynamic performance of an unconventional two-spool flow control servo valve using a pressure control pilot is analyzed. Such valves are less expensive than typical servo-valves but also tend to be limited in their dynamic performance. Based on a previously developed eight state nonlinear model [1], we develop a simplified linear model which is able to capture the essential dy...
