Speed-Control of Energy Regulation Based Variable-Speed Electrohydraulic Drive
Strojniški vestnik – Journal of Mechanical Engineering, 2013 The variable-speed electrohydraulic drive is a promising drive principle due to its high energy efficiency and large speed-range. However, its slow response and poor low-speed behaviour limit its application. To address these disadvantages, a energy regulation based variable-speed electrohydraulic drive is proposed.
