A sliding mode based active center of gravity control law is designed for the aircraft with center of gravity varying during flight. As the basis, the general scheme of the active center of gravity control system is proposed, and the mathematic model of aircraft center of gravity varying with fuel transfer is established. Then, the center of gravity control law based on sliding mode control theory...
Active center of gravity control can transfer fuel among many fuselage fuel tanks to effectively optimize aircraft center of gravity and gain the potential economic performance benefits. In-flight possible failures in the fuel system may generate direct influences on aircraft center of gravity control. The aim of this article is to investigate the influence of partial fuel transfer line leak on the...
Aircraft centre of gravity (C.G.) is important for aircraft safety and performance. This paper proposes the use of Gaussian process regression (GPR) models for the estimation of the C.G. location of fixed-wing aircraft. The major benefit of using a GPR model is that it is a data-based approach explicitly tackling uncertainties caused by the quality and quantity of the data as well as sensor measurement...
