Hydraulic actuator control help - any specialists out there?
Hi
So, I'm involved in building a suspension test rig (a bit like a very specialised shaker rig) and we're doing it from scratch. I am
wondering if there's anyone who can point me in the right direction?
We have most of the gear for what we need - pump, accumulator, etc. is sorted. The ram with the right force/stroke/velocity requirements is sorted,
and an electro-hydraulic valve is also sorted. Someone to write the code to manage this is also sorted (me).
What we're lacking in the middle is an understanding of how to control the valve. It does have some analogue inputs, but what seems to be
lacking is any PID control (or other) in order to put the ram where we want it when we want it. I can't help thinking there's got to be a
kind of digital controller that will take a signal (either analogue or serial) for position, speed, force. What I'm trying to avoid is actually
having to write and tune PID controllers if there's an off-the-shelf module that is already designed for this. Then, I can just send it either
the data we have after appropriate manipulation and signal processing.
Any ideas?
Thanks
Mark

Is Pid control that hard to impliment. I have done one in asembly language, in a high level language it is really easy. I can speak later about
implimentaion if interested.

Well, I'd sooner have a PID module I can send a variety of real time track data to, rather then implement one of my own.
Saying that, I really appreciate the support.
Thanks

Is a good start, worked well for me to start.
