For achieving higher energy efficiency in slower systems, direct pump control replacing fast-response valve control is being put in place through variable-speed motors. Despite the promise of a quicker response, displacement control of pumps has seen slower progress for exhibiting undesired oscillation with respect to the demand in some situations. Hence, a mechatronic simulation-based design is taken up here for a variable-displacement pump\u2013controlled system directly feeding a double-acting single-rod cylinder. The most significant innovation centers on designing an axial-piston pump with an electrohydraulic compensator for bi-directional swashing. An accumulator is conceived to handle the flow difference in the two sides across the load piston. A solenoid-driven sequence valve with P control is proposed for charging the accumulator along with setting its initial gas pressure by a feedforward design. Simple proportional\u2013integral\u2013derivative control of the compensator valve is considered in this exploratory study. Appropriate setting of the gains and critical sizing of the compensator has been obtained through a detailed parametric study aiming low integral absolute error. A notable finding of the simulation is the achievement of the concurrent minimum integral absolute error of 3.8\u2009mm\u2009s and the maximum energy saving of 516\u2009kJ with respect to a fixed-displacement pump. This is predicted for the combination of the circumferential port width of 2\u2009mm for the compensator valve and the radial clearance of 40\u2009\u00b5m between each compensator cylinder and the paired piston. <\/jats:p>","DOI":"10.1177\/0959651820973898","type":"journal-article","created":{"date-parts":[[2020,12,1]],"date-time":"2020-12-01T07:27:17Z","timestamp":1606807637000},"page":"1218-1236","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Energy-saving design of variable-displacement bi-directional pump-controlled electrohydraulic system"],"prefix":"10.1177","volume":"235","author":[{"given":"Samir","family":"Kumar Hati","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Asansol Engineering College, Asansol, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5215-0081","authenticated-orcid":false,"given":"Nimai","family":"Pada Mandal","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, NIT Patna, Patna, India"}]},{"given":"Dipankar","family":"Sanyal","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Jadavpur University, Kolkata, India"}]}],"member":"179","published-online":{"date-parts":[[2020,11,30]]},"reference":[{"key":"bibr1-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1016\/j.rser.2014.04.036"},{"key":"bibr2-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1109\/TMECH.2013.2265312"},{"key":"bibr3-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1243\/09596518JSCE681"},{"key":"bibr4-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1109\/TMECH.2011.2165958"},{"key":"bibr5-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1016\/S0957-4158(03)00067-9"},{"key":"bibr6-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1177\/0959651813512820"},{"key":"bibr7-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1016\/j.autcon.2009.04.005"},{"key":"bibr8-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1243\/09596518JSCE580"},{"key":"bibr9-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1016\/j.conengprac.2014.05.005"},{"key":"bibr10-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1016\/j.enconman.2014.06.073"},{"key":"bibr11-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1016\/j.ast.2018.02.030"},{"key":"bibr12-0959651820973898","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1099-1239(199706)7:6<591::AID-RNC293>3.0.CO;2-M"},{"key":"bibr13-0959651820973898","unstructured":"Vickers INC.
