Position control of hydraulic motor system

Fluid power systemsare used in a wide variety of applications ranging from precision control systems such as robotics and aerospace to heavy industrial systems such as steel rolling mils, power machines and plastic industry.Firstly some studies about this issue are given, hydraulic power control is examined and hydraulic circuit elements are recognized.After that, the properties of system that used in simulation are given; proportional valve flow rates and the mathematical model of the system are formed. Equations are solved by Matlab Simulink and velocity, position, flow rates and pressure figures of the system are obtained. PD and PID control algorithms are applied to the system.Keywords: Hydraulic motor, hydraulic modeling, PD, PID, simulation
