Hydraulic servo actuators

simulation of Hydraulic servo actuators

Hydraulic servo actuators (HSAs) are used to precisely control displacement in a wide range of equipment. Generally, a hydraulic servo actuator consists of a hydraulic actuator controlled by a directional control valve of an infinite number of positions and equipped with a feedback arrangement. This simulink file simulated the dynamic behavior of a hydraulic servoactuator. The simulation program is based upon a detailed nonlinear model and a transfer function. The construction, operation, applications and mathematical models are given in my book: M Galal Rabie, Fluid power Engineering, McGraw-Hill, NY, May 2009.
