Modeling and Simulation of Redundancy Management of Electro-Hydrostatic Actuator
2020Electro-hydrostatic actuators are widely used in the aerospace field, they are an important part of aircraft flight controls. This paper presents the redundancy management model of electro-hydrostatic actuators. First, the failure mode of the inverter is analyzed, then the structure layout of the three-redundancy inverter is proposed, and the fault ...

Design and Characterization of a Dual Electro-Hydrostatic Actuator
2011Actuation of flight surfaces in aircraft have evolved over the last century from systems using simple mechanical linkages actuated by the pilot to complex electronic systems that maneuver large loads and have some form of redundancy. The latest form of flight surface actuation uses Power-By-Wire (PBW) systems, which are modulated, lean and fault ...
