As applications of forming equipment become increasingly widespread, the demand for low
cost and significant energy-saving schemes gets stronger and stronger. A partitioned energy-
saving control for drive system was first proposed to match the installed power of hydraulic
system with the demanded power of grouped hydraulic presses, in which the drive system is
partitioned into several drive zones according to the load profiles of different operations. The
configuration and strategy of the control for grouped hydraulic presses are constructed …
