Abstract

Hidraulika je sastavni dio mnogih industrijskih pogona te se stoga redovito istražuju bolji i jednostavniji načini rada i upravljanja hidrauličkim sustavima. Energetska učinkovitost jedan je od najvažnijih faktora prilikom novih istraživanja i zato su realizirani izravno pogonjeni elektrohidraulički sustavi. Cilj ovog rada je usporediti potrošnju energije izravno pogonjene hidraulike i klasične hidraulike, koja koristi proporcionalni ventil za upravljanje. U radu su također opisane prednosti i mane hidraulike te su opisani principi rada proporcionalne i izravno pogonjene hidraulike. Opisan je postupak određivanja koeficijenata PID regulatora za oba sustava kao i postupak estimacije mase tereta.

Abstract (english)

Hydraulics is constituent part of many industrial plants and therefore better and simpler modes of operation and control modes of hydraulic systems are being researched regularly. Energy efficiency is one of the most important factors in new researches and therefore directly driven electrohydraulic systems have been realized. The main purpose of this work is to compare energy consumption of directly driven hydraulics and conventional hydraulics, which uses proportinal valve for control. This work describes advantages and disadvantages of hydraulics and operation modes of proportional and direct driven hydraulics. Determination procedure of PID parameters is described as well as load mass estimation.
