Pressure control in hydraulic systems with variable or constant pumps?Lovrec, Darko (Avtor) Ulaga, Samo (Avtor) automatic control engineeringhydraulic systemspressure controlconstant pumpsThe paper deals with electrohydraulic supply systems with variable (adjustable( supply pressures. Two control concepts are used in practice: the pressure control concept using a variable pump and constant speed of the driving electric motor as the commonly used concept, and the pressure control concept with a constant pump and a speed-controlled electric motor as the alternative concept. The typical features and the applicability of both conceps, as well as their dynamic responses are studied in this work.20072012-05-31 11:12:18Neznano25907UDK: 681.5COBISS_ID: 11193110ISSN pri članku: 0732-8818NUK URN: URN:SI:UM:DK:TFAQHPL5sl
