摘　　要：飞行器油箱内油量的分布和供油策略会导致飞行器质心的变化,因此,制定各油箱的供油策略是飞行器控制的一项重要任务.对于给定的飞行器,分别在其平直飞和俯仰状态下,给出了其质心的计算方法,并根据飞行的相关数据和要求,建立数学模型,使得飞行器质心与理想质心欧氏距离的最大值达到最小.为了求解该数学模型,提出了一类基于二次规划的求解方法,并求得了各油箱相应的供油速度曲线.此外,还给出了飞行器各油箱初始油量分配的一种方法.数值实验表明所提算法有效且精度较高.The distribution of fuel in the tank and fueling strategy will lead to the change of aircraft centroid.Therefore,formulating a fueling strategy for each tank is an important task for aircraft control.For a given aircraft,this paper gives the calculation method of its centroid in level flight and pitch respectively.Further,according to the relevant data and requirements of the flight,a mathematical model is established to minimize the maximum of Euclidean distance between the aircraft centroid and the ideal aircraft centroid.In order to solve the mathematical model,we propose a kind of method based on quadratic programming,and obtain the corresponding fuel supply speed curve of each tank.In addition,this paper presents a method for the initial fuel distribution of each tank of the aircraft Numerical experiments demonstrate that the proposed method is effective and accurate.
