Using high-speed on-off valves (HSVs) with small size, low cost, and high switching
accuracy instead of expensive proportional/servo valves, and researching high-performance …

A pneumatic actuator is a fast and economical tool that converts compressed air into
mechanical motion. In this paper, an extended state observer (ESO)-based sliding mode …

The pneumatic pressure control systems have been used in some fields. However, the
researches on pneumatic pressure control mainly focus on constant pressure regulation …

Atmospheric pressure is a weather element that must be observed in the field of
meteorology. Electronic barometers, aneroid barometers, mercury barometers are generally …

This paper presents a miniaturized didactic device for experimenting with the feedback
control of air pressure in a vessel, called the PressureShield. The apparatus is built on a …

Investigating the ability of a pneumatic actuator to exhibit the desired mechanical impedance
is the subject of this article. Inertia, stiffness and damping are three components of …
