However, the overall system efficiency for multiple actuators is still low since this centralized hydraulic control system only adapts to the highest load pressure. Therefore, in this article, a distributed hydraulic control system where each function is powered by a hydraulic free piston engine is proposed. Compared with centralized solution, it is more efficient since the power of hydraulic free piston engine is tailored to each function. By integrating small inertia linear engine and pump piston in one unit, the hydraulic free piston engine is an efficient and fast response hydraulic power source. Since the hydraulic free piston engine is essentially a digital hydraulic power source, a digital load-sensing control is proposed in this study. The system architecture, modeling, controller design and performance of the digital hydraulic load-sensing control system are presented. A test bench is developed to verify the system feasibility and performance.<\/jats:p>","DOI":"10.1177\/09596518231154455","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T02:47:11Z","timestamp":1676515631000},"page":"1147-1160","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["A novel hydraulic load-sensing control solution to working functions of mobile machine"],"prefix":"10.1177","volume":"237","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9159-6679","authenticated-orcid":false,"given":"Feng","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Fluid Power and Mechatronic Systems, School of Mechanical Engineering, Zhejiang University, Hangzhou, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9198-3038","authenticated-orcid":false,"given":"Jiaming","family":"Wu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Fluid Power and Mechatronic Systems, School of Mechanical Engineering, Zhejiang University, Hangzhou, China"}]},{"given":"Bing","family":"Xu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Fluid Power and Mechatronic Systems, School of Mechanical Engineering, Zhejiang University, Hangzhou, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9929-4085","authenticated-orcid":false,"given":"Zongxuan","family":"Sun","sequence":"additional","affiliation":[{"name":"NSF Engineering Research Center for Compact and Efficient Fluid Power, Department of Mechanical Engineering, University of Minnesota, Minneapolis, MN, USA"}]}],"member":"179","published-online":{"date-parts":[[2023,2,15]]},"reference":[{"key":"bibr1-09596518231154455","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2021.3051555"},{"key":"bibr2-09596518231154455","doi-asserted-by":"publisher","DOI":"10.3390\/en10050647"},{"key":"bibr3-09596518231154455","doi-asserted-by":"publisher","DOI":"10.1007\/s11465-018-0470-5"},{"key":"bibr4-09596518231154455","first-page":"125","volume-title":"Internationales Fluidtechnisches Kolloquium (IFK)","volume":"1","author":"Pedersen HC"},{"key":"bibr5-09596518231154455","doi-asserted-by":"publisher","DOI":"10.1243\/PIME_PROC_1988_202_012_02"},{"key":"bibr6-09596518231154455","doi-asserted-by":"publisher","DOI":"10.1115\/1.2896436"},{"key":"bibr7-09596518231154455","doi-asserted-by":"publisher","DOI":"10.3901\/CJME.2004.01.031"},{"key":"bibr8-09596518231154455","doi-asserted-by":"crossref","unstructured":"Wagner ZD.
