Summary

Summary

A unique resource that demystifies the physical basics of hydraulicsystems

Hydraulic Control Systems offers students and professionals areliable, complete volume of the most up-to-date hows and whys oftoday's hydraulic control system fundamentals. Complete withinsightful industry examples, it features the latest coverage ofmodeling and control systems with a widely accepted approach tosystems design.

Hydraulic Control Systems is a powerful tool for developing a solidunderstanding of hydraulic control systems that will serve thepracticing engineer in the field. Throughout the book, illustrativecase studies highlight important topics and demonstrate howequations can be implemented and used in the real world.

Featuring exercise problems at the end of every chapter, HydraulicControl Systems presents:
* A useful review of fluid mechanics and system dynamics
* Thorough analysis of transient fluid flow forces withinvalves
* Discussions of flow ripple for both gear pumps and axial pistonpumps
* Updated analysis of the pump control problems associated withswash plate type machines
* A successful methodology for hydraulic system design-startingfrom the load point of the system and working backward to theultimate power source
* Reduced-order models and PID controllers showing controlobjectives of position, velocity, and effort


Author Notes

NOAH D. MANRING is James C. Dowell Associate Professor and Director of Graduate Studies in the Mechanical and Aerospace Engineering Department at University of Missouri-Columbia (UMC). Before joining the faculty at UMC, he worked for eight years in the off-highway mobile equipment industry. He holds ten U.S. patents for innovations in the field of fluid power. As a professor, he has received research funding from Caterpillar, Inc., Festo Corp., and the National Fluid Power Association, among others, as well as the U.S. Department of Education, the National Science Foundation, and various private donors. He currently serves as an associate editor of the International Journal of Fluid Power and the Journal of Dynamic Systems, Measurement, and Control. He has done consulting work for several industrial firms including Moog Inc., FMC Wyoming Corp., Dennison Hydraulics, and Parker Hannifin.
