The present work is directed to develop the dynamic performance of an electro-hydraulic proportional system (EHPS). a mathematical model of (EHPS) is presented using electrohydraulic proportional valve (EHPV) by the aim of Matlab-simulink which facilitate the simulation of the hydraulic behavior inside the main control unit. Experimental work is done and closed loop system is designed using linear variable displacement transducer sensor (LVDT). The controller of the system is an Arduino uno which is considered as the processor of the system. The model is validated by the experimental system. The study also presents a real time tracking control method based on pulse width modulation by controlling the speed of the actuator to achieve position tracking with minimum error.
