Position Controller for Direct Driven Electro-Hydraulic System

International 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

A Smart Fluid‐Hydraulic System Based on MRF Valve Control and Its Application in Flexible Grasping

Advanced Science, EarlyView.
This study introduces a smart fluid hydraulic system using MRF valve control for flexible gripping. An MRF‐MSV with an integrated excitation coil and micro‐textured damping channels is designed and validated; micro‐texturing increases hydraulic resistance. Coupled with a soft actuator, the MRF‐MSV enables dynamic bending and grasping.
