To minimize wasted energy in hydraulic systems, variable-displacement pumps were developed. They reduce power loss by adjusting the relationship between pressure and flow for various power levels.

Abstract: Energy efficiency remains one of the most important unsolved challenges in hydraulic (robotic) systems, especially in off-highway machines and ambulatory robotic systems where the energy ...

Abstract: An E/H control design is proposed for load sensing with power limit control of hydraulic variable displacement pumps. The pump operation mode will be either in pressure control or ...
