Position control of a hydraulic system with PID algorithm

Hydraulic systems are widely used in many industrial applications that require high performance, high torque in small volumes, force and precise position control is requiring. Therefore, realistic modeling of hydraulic systems and controller design maintain up to date.Although several advanced control strategies have been developed, PID control method is one of the oldest and mostly used control method among feedback controller. PID controllers have been widely used in industrial applications because of their simple structure, robust performance, easy comprehension and quite easy tuning. Widespread use of this has motivated many researchers on design of PID controller.In this study, a parameter research was made for PID control by the means of achieving a realistic simulation of a hydraulic position system which is driven by a proportional valve. In consequence, the outcomes which are obtained by implementing a hydraulic system?s position control with PID algorithm in MATLAB/Simulink were discussed.KEYWORDS: Ionosphere, magnetosphere, electron density trough, critical frequency.
