    摘要:

    为解决传统空中加油对接过程中受油机纵向轨迹跟踪控制存在时间滞后的问题,提出一种基于直接升力 的空中加油对接飞行控制方法。采用非线性 L1 制导的方法生成横纵向加速度指令,设计 2 种直接升力方案对受油机 纵向轨迹控制加以改进,采用动态逆方法对姿态回路设计,通过扩张状态观测器对动态逆内回路进行补偿。仿真结 果表明:采用的 2 种方案均能消除纵向轨迹跟踪的时间滞后,实现受油机纵向轨迹的快速响应,完成空中加油的成 功对接。

    Abstract:

    In order to solve the problem of time lag in the longitudinal trajectory tracking control of the receiver aircraft during the traditional aerial refueling docking, a docking flight control method based on direct lift was proposed. The nonlinear L1 guidance method was used to generate the longitudinal and transverse acceleration commands, and two direct lift schemes were designed to improve the longitudinal trajectory control of the receiver aircraft. The attitude loop was designed by the dynamic inverse method, and the dynamic inverse internal loop was compensated by the expanded state observer. The simulation results show that two schemes can eliminate the time lag of longitudinal trajectory tracking, realize the rapid response of longitudinal trajectory of the receiver aircraft, and complete the successful docking of aerial refueling.
