Hydraulic transformer can improve the transmission efficiency of the hydraulic system. As the manual hydraulic transformer cannot achieve automatic control and remote control in the hydraulic system, to meet this challenge, the electro-hydraulic servo plate-inclined plunger hydraulic transformer (EHHT) was proposed in this paper. First, through analyzing the principle of the EHHT, the structure of EHHT is designed based on the theoretical analysis; Secondly, the mathematical model and simulation model of output pressure were created. Finally, the fuzzy control strategy was designed and tested on the experiment bench. Both the simulated and experimental results show that the control strategy can effectively improve the pressure control performance of hydraulic transformer and the theoretical analysis is correct.
