Electro‐mechanical actuators for general aviation fly‐by‐wire aircraft

Aviation, 2005
A long‐term goal for general aviation aircraft is to reduce or eliminate the use of fluid power systems such as hydraulics from the aircraft. Power‐By‐Wire (PBW) technology seems to be the next major step in the development of aircraft control.

Modal Space Feedforward Control for Electro-Hydraulic Parallel Mechanism

IEEE Access, 2019
As a parallel mechanism with six-degree-of-freedom, an electro-hydraulic shaking table is endowed with strong coupling characteristics among different degree-of-freedoms. When the electro-hydraulic shaking table moves to one direction, there will be some

Backstepping Control of Electro-Hydraulic Arm

2018 6th International Conference on Control Engineering & Information Technology (CEIT), 2018
In this study, positioning control of the electro hydraulic systems is considered. Backstepping control strategy is designed by defining an auxiliary error signal. The performance of the controller is investigated by conducting numerical simulations. From the simulation results, it is seen that the control objective achieved successfully.
