Figure 15. (A) Physical architecture of the energy matching method[55] and (B) pneumatic experimental prototype. (In the figure, the drive system is divided into N drive zones according to the number of working stages of the hydraulic press in a forming process; and the output power Pi of each drive zone matches the required power of the hydraulic press working in the corresponding working stage).
