Electro-Hydraulic Servo System

Abstract

This project concerns of building an electro-hydraulic servo system model to be used in the industrial hydraulics lab to achieve the controlling of a hydraulic flow and pressure using a hydraulic servo valves, understanding the internal construction and the operational principles of servo hydraulic valves, understanding the mathematical model of a simple hydraulic system using hydraulic servo valve. The mathematical model for the built system was constructed and the simulation for linear mathematical model was done, and showed that the instability of the system and large steady state error. So indeed the system need an external controller to be designed.
