Analysis of energy consumption for the electro-hydraulic actuation system with different pressure levels

To meet the needs of saving energy for high pressure and high power airborne electro-hydraulic servo actuation system, adopting different pressure systems according to different flight missions may be useful. This paper describes the mathematic models of the 21MPa actuation system and the 35MPa actuation system, and simulates models with MATLAB/Simulink. The simulation obtains perfect dynamic performances and detailed comparison results about energy and efficiency. Then simulate F16 model with the actuation systems of different pressures. The results show the influence of 21MPa actuation system for the flight performance is almost same as that of 35MPa; verify the 21MPa actuation system saving more energy.
