H Tipi Hidrolik Presin Modellenmesi Ve Konum Geri Beslemeli Oransal-Türevsel Kontrolü

Abstract

In this study, modeling and position feedback proportional-derivative control of industrial 300 tons H-type hydraulic press is realized using a different modeling approach. In this modeling approach, obtaining of behavior of motion of whole system is aimed without using Newton, Lagrange and fluid dynamics equations. Firstly, mechanical motion of press is defined by importing solid model drawn in SolidWorks program to MATLAB/SimMechnanics program. Then obtained model is combined with hydraulic model designed in MATLAB/SimHydraulic program includes hydraulic power unit, valves, cylinders and other components and thereby a model is formed which simulates mechanical and hydraulic motion of press. After these works, proportional-derivative control of all system is realized via position feedback from press model. Finally, realistic simulation model and position feedback control of hydraulic press are realized successfully and obtained controlled stroke, valve displacement, pressure and flow results are presented and interpreted
