Abstract
The angle-of-attack signal is very important for modern fly-by-wire flight control system aircraft.The inconsistency of the local airflow on both sides of the nose will cause the difference of the angle-of-attack signal.The signal-monitoring voting logic of the flight control system will judge the angle-of-attack signal and make the angle-of-attack availability decrease.By studying the relationship between the lateral overload and the side-slip an-gle,the side-slip angle is estimated by the lateral overload,the angle-of-attack signal correction method based on the side-slip angle estimation and the complete monitoring voting algorithm is established to improve the availabili-ty of the angle-of-attack signal under the condition of large side-slip.The simulation results show that the proposed method is successful in estimating the side-slip angle,and the angle-of-attack signal on both sides of the nose is consistent with the modified side-slip angle,which solves the problem of over-error of the angle-of-attack signal caused by the large side-slip state and has good correction effect.关键词
