Design and Control of Hydraulic systems using
vibration based diagnosis. Edition No. 1
VDM Publishing House, Oct 2008, Pages: 208
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.
