Sažetak
In the past few years, decentralized hydraulics gain advantage over classical hydraulics due to lower energy consumption, lower pressure losses in pipelines and easy automatization. In this paper, Direct Driven Electro-Hydraulic (DDEH) drive is made in parallel with a classical proportional hydraulic system. In DDEH control method the valve is replaced with reversible pumps/motors which are directly controlled with a servo motor. Such systems combine best properties of both hydraulic and electric drives. Proposed experimental setup is designed for easy switching between both systems which allows exact comparison of obtained experimental results. The nonlinear models of both systems have been derived using PID controller and simulated in Matlab program. Finally, the conclusion regarding precise position control and system dynamics is given in detail.
