This book deals with the design and control ofhydraulic systems and using the system componentssignature as an input to control the system pump andmonitoring the health of the system in real timeenvironment. The book starts with listing some problems that canbe encountered in the systems and redesigning thepump to improve the system performance. Then, thepipe dynamics is studied with different boundaryconditions and the study includes the effect of thepump pulsation on the pipe response. New control strategy is introduced to minimizevibration levels, reduce the rise time, and to reducenoise levels. Then, it is generalized to control thepump flow according to load requirements and pipevibration levels. A compensation factor is introducedto moderate the negative impact of the pipevibrations, and to generate a new set value for theinclination angle. For timely detection of faults, the application ofwavelet analysis to detect different defects isexamined. Some defects are produced, such as pipeflutter, pump dynamic instability, and voltageunbalance in driving electric motor. Suggestionsfor future work are proposed.
Since launching the first textbook rental site in 2006, BookRenter has never wavered from our mission to make education more affordable for all students. Every day, we focus on delivering students the best prices, the most flexible options, and the best service on earth. On March 13, 2012 BookRenter.com, Inc. formally changed its name to Rafter, Inc. We are still the same company and the same people, only our corporate name has changed.
