As you guys know I sell hydraulic motion controllers. We keep getting the question "why should I spend all that money on a hydraulic motion controller"
At the same time Alan Hitchcock, the Hydraulics and Pneumatics editor, thought that this would make for a good article. So here it is. I tried not to be biased.

Any comments? There is one sentence that might grab peoples attention.
BTW, I am not done yet. There will be a part 2 where I go into using PI, PD and PID control and the need for a target generator.
I also play to have a part 3 where we actually implement a hydraulic motion controller in a PLC. We have already done this on a S7-1500. I hope to also compare with a CompactLogix.
BTW, thanks to Norm Dziedzic I got an early warning the Fig 2 and Fig 3 were exchanged so we got that corrected.
