Design, Analysis, and Verification of an Electro- Hydrostatic Actuator for Distributed Actuation System [PDF]

open access: yesSensors, 2020
In order to provide a simplified and low-cost solution of the terminal for a distributed actuation system, this paper proposes an electro-hydrostatic actuator (EHA) based on the linear drive principle. The proposed actuator is directly driven by a linear pump with a collaborative rectification mechanism, whose performance relies on the collaboration of
