In steam turbine control and actuation, the valve plays a key role in operability reliability. The electrohydraulic regulating system for valve, usually called servomotor, needs to be reliable high performing under nonlinear excitation interference actual conditions. Currently, servo technology is widely used servomotors. Although this has good performance, it still some technical defects, such...

This paper deals with the position control of a hydraulic actuator regulated by a proportional directional control valve. The control algorithms based on the proportional-derivative controller have been applied to a specially designed two-channel electro-hydraulic servo system, which has the capacity to experimentally simulate common circumstances of a typical fluid power circuit. The first sys...

The sonochemical coprecipitation reaction with moderate ultrasound irradiation in a low vacuum environment was used to obtain aqueous colloidal suspensions of iron oxide nanoparticles (IONPs). synthesized magnetite were conjugated directly by folic acid using electrohydraulic discharges as processing technique before modification the surface nanoparticles. Electrohydraulic applied two operation...
