Mathematical modelling of electrohydraulic servovalve system
Electrohydraulic servo valve (EHSV) uses lower power electrical signals for controlling the movements or positions of large power hydraulic pistons or motors. The electrohydraulic system is widely used in marine and aerospace industries, which require fast and accurate response, such as aircraft con...

Electrohydraulic servo valve (EHSV) uses lower power electrical signals for controlling the movements or positions of large power hydraulic pistons or motors. The electrohydraulic system is widely used in marine and aerospace industries, which require fast and accurate response, such as aircraft controls and numerically controlled machine tools.
Mathematical modeling based on control theory and fluid power system was developed for electrohydraulic servo-valve system. The parametric variation of each component in the modelled hydraulic system was carried out, and a computer simulation software, MATLAB, was employed in the analyses, so as to gain a better understanding of the parametric variation effects on the stability and response of the electrohydraulic servo valve system. The proportional integral derivative (PID) controller was incorporated into the transfer function of the mathematical model in order to fine tune the system stability and dynamic response when the system is subjected varying input loading conditions. |
