An Engineering Analysis of the Pulse Width Modulation Method of Controlling Output Pressure of a Hydraulic Power Supply, Jack L. Johnson, PE,
This is a detailed engineering study of a pressure compensated system that uses a fixed displacement pump, but NO relief valves (it IS as efficient as a conventional pressure compensated pump). You can read about the very complete test results, but more importantly, you can learn all that you need, to design and build your own low cost, but efficient constant pressure power units for both servo and conventional applications. Goodbye, variable displacement pumps.

Electrohydraulic Control of Pressure and Cylinder Force, Jack L. Johnson, PE,
Control of pressure is vital to controlling force or torque from actuators. It is subject to the constraints of the system non-linearities. This book presents all the mathematical wizardry needed to design effective, predictable and controllable pressure control systems by electrohydraulic means. It introduces ways to control gauge and differential pressure and also covers the problems associated with control of cylinder output force.

Lexicon – Electrohydraulics and Motion Control, Jack L. Johnson, PE,
This illustrated lexicon is unique in that it is cross-referenced to related terms in the book. If the current definition contains an unfamiliar term that is in bold, merely look that term up and complete your understanding. It uses electric-hydraulic analogies so that you can use your own knowledge of hydraulic circuits and concepts to understand the electronic analogy. More than 700 terms are defined in this very comprehensive lexicon.

Lab Lecture: Effects of Changing Inertia on the Performance of the Electrohydraulic Servomechanism, Jack L. Johnson, PE,
Commonly referred to as the "Four Inertias Video", this CD contains a laboratory demonstration (approx 24 minutes) of the method and a lecture (approx 50 minutes) to explain the principles behind the laboratory procedures. You will see in the demonstration how increased loading of the cylinder with inertia creates a steadily decreasing system performance. The DVD recording also contains a searchable pdf file of background material and a verbatim transcript of the narrations of the two videos.

Four Methods for Dealing with the Difficult System, Jack L. Johnson, PE,
Commonly referred to as the "Four Methods Video," the CD contains a laboratory demonstration (approx 24 minutes) of the method and a lecture (approx 50 minutes) to explain the principles behind each of the four methods used to control the "difficult application." When confronted with a system with a low hydromechanical resonant frequency and simple solutions cannot be applied, or don’t work, this video explains some of the alternatives. It shows you how to increase damping and what benefits can be expected. An accompanying lecture explains the theory and concepts behind the video methodology.
