Analysis on rigidity of hydraulic hoses for electro-hydrostatic actuators
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017Electro-hydrostatic actuators (EHAs) are said to have potential as actuators for robotic systems because they have high power-to-weight ratio, compact, and energy saving systems compared to general hydraulic systems. However, modeling approaches and analyses on dynamic characteristics have not been quite concrete yet. In order to expand EHAs' potential

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.

Analysis for the power loss of electro hydrostatic actuator and hydraulic actuator
2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015This article describes the difference between traditional airborne hydraulic actuator and electro hydrostatic actuator in heat dissipation. The power loss of the two systems are analyzed based on the method of energy transfer under different working conditions.

Modeling and Identification of an Electro-Hydrostatic Actuator
IFAC Proceedings Volumes, 2010Abstract The aim of this paper is to develop an accurate model of an electro-hydrostatic actuator (EHSA) and to estimate the model parameters. The physical behavior of each components has been analyzed and a linear model has been obtained. Then, the cylinder friction phenomenon and the cylinder chambers volume variations have been considered and a ...
