The modelling approach presented enables a reduction of the control system development time for a complete excavator, while providing accurate system dynamics. A tool for defining an appropriate control strategy is a key point for satisfying the need for systems with better energy- efficiency. Moreover, the model will be a significant support in investigating energy recovery solutions and evaluating the suitability of hybrid solutions (mechanical/hydraulic/electric). The hydraulic model, composed of the pump's grey box model and the valve block white box model, has been validated on the basis of a set of experimental data collected on a test bench. The results of this study are presented in this paper"},{"@xml:lang":"sl","#text":"Najnovejše raziskovalne dejavnosti na področju mobilne hidravlike so usmerjene predvsem v optimizacijo sistemov, opredeljevanje novih konfiguracij sistemov in hibridizacijo sistemov. Vsi omenjeni pristopi so namenjeni varčevanju mobilne hidravlike z energijo za zmanjšanje porabe goriva in emisij onesnaževalcev. Za optimalno izkoriščanje novih sistemskih konfiguracij je treba razviti tudi optimalne strategije krmiljenja. Zato se povečuje zanimanje za razvoj novih sistemskih rešitev in njihovih strategij krmiljenja. Matematična orodja za opredelitev ustreznih krmilnih strategij so ključnega pomena za zadovoljitev zahtev po zanesljivejših in učinkovitejših sistemih. Pristop k matematičnemu modeliranju in metodologija, ki sta opisana v tem članku, obravnavata problem primernega dinamičnega modela sistema in kratkega računskega časa. Predstavljena metodologija je bila uporabljena za hidravlični bager.
