But Robert Burton certainly was. He authored countless books and technical paper covering closed-loop control of electrohydraulic systems.

And even though his works wer published about 20 years ago, he insight into the behavior of loads, hydraulic flow and pressure, and electronic control are just as relevant today.</p></div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/hitch-post">The Hitch Post</a></li> </ul></div><p><a href="http://hydraulicspneumatics.com/blog/how-calculate-loop-gain-electrohydraulic-servo-systems" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/how-calculate-loop-gain-electrohydraulic-servo-systems#comments Controls & Instrumentation The Hitch Post Fri, 29 May 2015 13:31:00 +0000 32721 at http://hydraulicspneumatics.com Hydraulics Becomes Art http://hydraulicspneumatics.com/blog/hydraulics-becomes-art <div class="node-body blog-body"><p>I&#39;ve never been to Rotterdam, Netherlands, and I probably never will.
