Abstract: In order to overcome self-excited high frequency oscillations and noise appearing sometimes during the working of hydraulic jet-pipe servo-valve, application of magnetic fluid (MF) in ...

Abstract: In a pneumatic driving system, a servo valve is most expensive equipment compared with pneumatic actuators. In a wearable driving system, the mass and size of a valve also becomes serious ...

The valves are opened and closed by the control voltage signal u(t), which is generated from the controller. This paper uses the PI controller to control the operation of the hydraulic actuator.
