Synopsis

This book deals with the design and control of hydraulic systems and using the system components signature as an input to control the system pump and monitoring the health of the system in real time environment. The book starts with listing some problems that can be encountered in the systems and redesigning the pump to improve the system performance. Then, the pipe dynamics is studied with different boundary conditions and the study includes the effect of the pump pulsation on the pipe response. New control strategy is introduced to minimize vibration levels, reduce the rise time, and to reduce noise levels. Then, it is generalized to control the pump flow according to load requirements and pipe vibration levels. A compensation factor is introduced to moderate the negative impact of the pipe vibrations, and to generate a new set value for the inclination angle. For timely detection of faults, the application of wavelet analysis to detect different defects is examined. Some defects are produced, such as pipe flutter, pump dynamic instability, and voltage unbalance in driving electric motor. Suggestions for future work are proposed.
