The regulation of displacement volume of the pump is carried out by means of an electro-hydraulic proportional valve, in parallel to which a conventional hydraulic pressure controller is connected. The control of the proportional valve is realized by a selective electronic amplifier. Unlike conventional systems with this type of pump control, this electronic amplifier receive a reference that is formed by an industrial controller with an embedded control algorithm. This makes it possible to implement advanced control techniques for control the basic energy parameters in hydraulic drives - pressure and flow. Presented experimental results show the operational capacity of the developed system.","PeriodicalId":150282,"journal":{"name":"2022 22nd International Symposium on Electrical Apparatus and Technologies (SIELA)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128764433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Where is All the Water? project is a multi-disciplinary research collaboration that has shown for the first time that low-cost sensor networks in combination with other technologies can respond to the Australian infrastructure problem of great distances and low population. It demonstrated that local gravity measurements - soon likely to be augmented with quantum sensing capability - are a technology that can help us map the underground and assist with quantifying recharge to the groundwater; and that satellites have an important role to play in the management of resources. Overall, large uncertainties are identified in water accounting, with the interaction between surface and groundwater being one of the major sources of uncertainty. Thus, innovative solutions to quantify the fluxes between above and below ground remains a priority.","PeriodicalId":150282,"journal":{"name":"2022 22nd International Symposium on Electrical Apparatus and Technologies (SIELA)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121412253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
