Research on fast response and high accuracy control of an airborne electro hydrostatic actuation system

Abstract

Modeling an airborne IElectro Hydrostatic Actuation (EHA) system with the nonlinear factors, saturation and dead zone. Based on double close loop control and variable gain predictive PD control, designed an innovation hybrid control scheme for the EHA. Its excellent characters consist of fast response, high accuracy, robustness and none overshoot. The scheme has been applied to an airborne EHA prototype successfully.
