A novel architecture of electro-hydrostatic actuator with digital distribution
Chinese Journal of Aeronautics, 2021 Abstract To address the flow imbalance rapidly of the asymmetric Electro-Hydrostatic Actuator (EHA), this paper presents a novel architecture of asymmetric EHA with the Digital Distribution (EHA-DD). It also improves the flow nonlinearity and control accuracy of the pump, especially in the low-speed condition.
