Hydraulic Systems Volume 2: Electro-Hydraulic Components and Systems by Dr. Medhat Khalil, Ph.D., CFPHS, CFPAI, from Milwaukee School of Engineering (MSOE) presents constructional and operational qualitative analogies between electrical, hydraulic, and electro-hydraulic systems. The book presents real-life examples of various types of electro-hydraulic valves, as well as the technicalities of in-field tuning of open-loop and closed-loop electro-hydraulic systems. The book also presents guidelines to select a valve for an application and a how-to-read data sheet of a valve. Basic functions contained in the electronic control units that drive EH valves are presented, including gain adjustor, maximum current limiter, ramp generator, pulse width modulation, dead band eliminator, and null adjustment current. The package includes a color textbook, electronic files for the animated hydraulic circuits, and a color workbook (sold separately) that contains printed PowerPoint slides, chapter reviews, and assignments.
