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
