Controller to operate linear actuator (constant speed, changing load)

I’m looking at controlling a linear actuator, that needs to be run at a constant speed relative to a changing load. I have a potentiometer to give the feedback signals and I wondered if you have anything in your range that would do this?

All our controllers can do that. The choice of one model or the other depends on the max amps needed by your actuator.
Our newest generation products have a more sophisticated algorithm that lets you define also the motion profile (max speed, acceleration and deceleration). See demo video at www.youtube.com/user/roboteqinc#p/u/0/xptBWoCq6Rc
At the end of the video, you will see the list of products that operate that way.
