how can i simulated electrohydraulic servo valve ?

Hello, i'm student from Bulgaria. I need help with Matlab simulink ! How to simulate tachometer connected to a hydraulic fixed motor? More specifically, how to convert angular speed of tachometer [rad / s] in current [V] to make feedback to the servo control electronic valve?

Thanks in advance!

You can use the Rotational Electromechanical Converter from simscape to change between the two realms. If you don't have simscape in your model you can view the source of the block if you do have the simscape library.

This type of conversion would be pretty basic in simulink where

voltage = K * angular_velocity;

where K is rad/s per unit voltage.
