How to Design Stable Closed-Loop Circuits

Robert Burton was an expert in electrohydraulic servo system design for more than 40 years. He contributed articles to Hydraulics & Pneumatics during the 1990s, and our September 1996 issue contains an in-depth article explaining electrohydraulic closed-loop control without of the complicated math that's often a part of tutorial material.

Robert Burton was an expert in electrohydraulic servo system design for more than 40 years. He contributed articles to Hydraulics & Pneumatics during the 1990s, and our September 1996 issue contains an in-depth article explaining electrohydraulic closed-loop control without the complicated math that's often a part of tutorial material.

If you're thinking a 20-year old article can't offer much for today's digital control systems, think again. The basics servo-system design remain the same, so if this is a subject you'd like to learn more about, click here to read his article.
