위그선의 종방향 운동 안정화를 위한 FBW 자세 조종성증강장치 설계

Abstract

In this paper the longitudinal control problem for the large WIG(wing-in-ground effect) craft is presented in the sense of the control augmentation system(CAS) derived by control surface of elevator. In order to achieve longitudinal stable systems, two mode of CAS are applied to the control systems which are pitch rate hold mode and pitch hold mode for cruise flight. Nonlinear model simulations are fulfilled to investigate the effectiveness of the applied CASs with and without wind disturbance.
