Review on electro hydrostatic actuator for flight control
International Journal of Fluid Power, 2016AbstractElectro Hydrostatic Actuator (EHA) is an emerging aerospace technology that aims at replacing centralised hydraulic system by a self-contained and localised direct drive actuator system. EHA has become an important part of modern flight control systems due to the increased efficiency, reduced leakages and lower overall weight compared to ...

MODELLING AND CONTROL OF AN ELECTRO‐HYDROSTATIC ACTUATOR
International Journal of Robust and Nonlinear Control, 1997The control of a novel aerospace actuator is considered, viz., an electro-hydrostatic actuator. It offers a high degree of maintainability and combat survivability of the aircraft's flight control system because all the actuator's elements are collocated.

The Nonlinear Accuracy Model of Electro-Hydrostatic Actuator
2008 IEEE Conference on Robotics, Automation and Mechatronics, 2008The electro-hydrostatic actuator (EHA) is a kind of power-by-wire (PBW) actuator. In this paper, a typical architecture of EHA is described and the block diagram model of EHA is established directly from the mathematic equations without transfer functions, which is a nonlinear accuracy model.
