Also improving the performance of (HSP) to achieve the position tracking in two degrees of freedom (2DOF) based on modifying the different parameters of the hydraulic circuit (actuator size – hydraulic servo actuator geometric configurationdifferent load on the platform) to achieve the best performance. The system offers a proposal for an upper stabilized platform with moving lower base to be used with ships to achieve a stabilization condition for many purposes such as radar. MATLAB Simulink and Simscape-multibody has been used in modeling the system. Changing the different parameters in the program block library input ...

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.
