Dear all, For a project I'm going to design a servo system that will output an amplified hydraulic pressure, whereas the input is a force or pressure as well (not per se hydraulic). Output and input must directly connected due to the force feedback. I don't have a lot of experience with either hydraulics nor creating systems like this so I want to read up some literature before starting on this. Are there any existing systems that incorporate this concept or do any of you know a good point where to start with this project? Thanks!
