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.</dc:description><dc:date>2007</dc:date><dc:date>2012-05-31 11:12:18</dc:date><dc:type>Neznano</dc:type><dc:identifier>25907</dc:identifier><dc:language>sl</dc:language></rdf:Description></rdf:RDF>
