Load-Sensing Pump Design to Reduce Heat Generation of Electro-Hydrostatic Actuator Systems
Energies, 2018 The electro-hydrostatic actuator (EHA) with variable pump displacement is considered to be a promising alternative to the currently popular EHA with fixed pump displacement in terms of heat reduction.

Research on Dual-Variable Integrated Electro-Hydrostatic Actuator [PDF]
Chinese Journal of Aeronautics, 2006 AbstractThe integrated electro-hydrostatic actuator (EHA) with variable displacement and variable rotation speed is researched. In the system, the output of the actuator is changed by controlling the rotation speed of the brushless DC servomotor and the displacement of the servopump. The mathematical model described in state space model is created. The

Modeling and control of an electro-hydrostatic actuator [PDF]
Proceedings of the IEEE 1995 National Aerospace and Electronics Conference. NAECON 1995, 2002 Advanced electro-hydrostatic actuators offer a high degree of maintainability and combat survivability of aircraft flight control systems, because all the components necessary to operate the actuator are collocated with the actuator. The quantitative feedback theory robust control method is used to design a controller for the actuator.
