| Abstract | ||||
| ABSTRACT: Hydraulic systems are widely used in many fields. Controlling of hydraulic system is carried out through several techniques. Proportional technique is considered one of the important and advanced techniques used to control hydraulic systems. Through this paper a complete model for a directional proportional valve has been built up using SIMULINK program to investigate the dynamic behavior of this class of valves. Experimental work has been conducted to measure the force exerted by the proportional solenoid and the flow rate through the directional proportional valve at different values of solenoid current. The experimental results have been used to validate the simulation program. The dynamic behavior of the electro-hydraulic proportional valve could be investigated using the obtained simulation program. | ||||
