Valve-less control is a new trend of electro-hydraulic servomechanism. It is possible to position the servo-cylinder directly by controlling the fluid volume discharged from an AC-servomotor drive pump. This paper discusses performance of this system on the point of preciseness, responsibility and stability. It shows efficiency of the system at low power.
