A variable frequency electro-hydraulic control system based on energy regulation was developed to improve slow respondence of the conventional variable frequency electro-hydraulic systems. An energy regulation device which could store redundant energy while hydraulic system was in decelerating period as well as release energy while the system was in accelerating period was employed in the variable frequency electro-hydraulic control system. This will enhance the dynamic characteristics of the variable frequency electrohydraulic control system. The experiments results which were compared with two other control systems showed that the variable frequency electro-hydraulic control system had excellent dynamic characteristics which like valve control systems. Furthermore, the throttle and relief energy loss of this system was little and even lower than conventional variable frequency hydraulic control systems.
