When the position error value is bigger than the threshold value, the system will transfer the pressure signal to the signal which will be added to the position signal, and regulate the system. This paper first builds a mathematical model of the hydraulic servo system position-pressure master-slave control, then simulates the system with AMEsim and Matlab softwares, which verifies the feasibility of this function. Finally, experiments are conducted using the new function, and the results show that position-pressure master-slave control can improve the precision and stability of hydraulic servo system; this new function can also be applied to other high speed, high precision and heavy equipment"},{"@xml:lang":"sl","#text":"Na univerzi za znanost in tehnologijo v Taiyuanu so bile razvite potujoče hidravlične škarje, ki se uporabljajo za rezanje jeklenih plošč debeline do 35 mm. Če debelina jeklenih plošč presega 35 mm, imajo potujoče škarje težave z rezanjem in podatki kažejo, da ni mogoče dovolj hitro vzpostaviti tlaka. Razlog je v tem, da škarje uporabljajo le zaprtozančno krmiljenje položaja in tlak ni pod nadzorom. Za razrešitev problema predlagamo novo funkcijo za glavno/podrejeno krmiljenje položaja/tlaka, ki lahko izboljša točnost položaja in tlaka. Zahteve krmiljenja položaja in tlaka so si navidezno v nasprotju, zato uspešno krmiljenje obeh parametrov predstavlja poseben izziv. Nova krmilna funkcija je zasnovana kot dvojen zaprtozančni sistem, kjer ima glavno vlogo krmiljenje položaja in sekundarno vlogo krmiljenje tlaka"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-H7CW8G06","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-H7CW8G06"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-H7CW8G06/ca7c53e9-6d41-4d64-914d-20514701e587/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-H7CW8G06/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-H7CW8G06"}}}}
