This paper analyses the current state of the art in linear actuation with digital hydraulics.
Based on the differences in their aims the paper partitions the area into four actuation …

Pulse number modulation (PNM) combined with pulse width modulation (PWM) control is an
effective solution to improve the resolution of digital valve systems. However, the numerous …

This paper presents the design and properties of a digital hydraulic valve system for
flowrates up to 400 l/min. The digital hydraulic independent metering valve system (DIMV) …

The article concerns the modelling and control of a digital hydraulic cylinder drive involving
a standard differential cylinder controlled by four digital flow control units in a full bridge …

The idea behind the parallel valve flow control concept is to use several on/off valves–of
either the same or different sizes–connected in parallel in order to simulate a variable orifice …
