Mass and charge transport in micro and nano-fluidic channels [PDF]

open access: yes, 2006
We consider laminar flow of incompressible electrolytes in long, straight channels driven by pressure and electro-osmosis. We use a Hilbert space eigenfunction expansion to address the general problem of an arbitrary cross section and obtain general ...

Position Controller for Direct Driven Electro-Hydraulic System

open access: yesInternational conference Fluid Power 2019: Conference Proceedings, 2019
In the past few years, decentralized hydraulics gain advantage over classical hydraulics due to lower energy consumption, lower pressure losses in pipelines and easy automatization. In this paper, Direct Driven Electro-Hydraulic (DDEH) drive is made in parallel with a classical proportional hydraulic system. In DDEH control method the valve is replaced

Robustness Analysis of an Electrohydraulic Steering Control System Based on the Estimated Uncertainty Model

open access: yesInformation, 2021
The impossibility of replacing hydraulic drives with other type drives in heavy duty machinery is the main reason for the development of a system for controlling hydraulic power steering. Moreover, the need for remote automatic control of the steering in
