Active Load-Sensitive Electro-Hydrostatic Actuator for More Electric Aircraft
Applied Sciences, 2020 In the flight control system, using an electro-hydrostatic actuator (EHA) instead of the currently used relatively mature electro-hydraulic valve-controlled actuator, there are three prevailing concerns, namely heating, size, and stiffness.

Position Control of a Single‐Rod Electro‐Hydrostatic Actuator Experiencing a Leaky Piston Seal
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 Single‐rod cylinders are generally employed in electro‐hydrostatic actuators (EHAs). A condition that is difficult to detect and could degrade the performance in single‐rod EHAs, is the faulty cylinder piston seal. It causes internal leakage from one chamber of the actuator to another.
