Electro-Hydrostatic Actuator (EHA) Position Tracking and Correction [PDF]
, 2015 The Electro-Hydrostatic Actuator (EHA) is a self-contained and modular hydraulic actuation system using feedback control. EHAs are being increasingly used in engineering and industrial systems that require high precision and efficiency such as aircrafts (Airbus 380), off-highway hydraulic hybrids and construction machineries.
