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

Modal Space Feedforward Control for Electro-Hydraulic Parallel Mechanism

IEEE Access, 2019
As a parallel mechanism with six-degree-of-freedom, an electro-hydraulic shaking table is endowed with strong coupling characteristics among different degree-of-freedoms. When the electro-hydraulic shaking table moves to one direction, there will be some
