| 中文摘要 |
| 在自动空中加油(AAR, automated aerial refueling)对接过程中, 加油机后方拖出的加油软管锥套受到加油机和受油机的双重气动干扰, 呈现不规则摆动运动, 受油机要实现与加油锥套的精确对接, 要求其飞行控制系统具有鲁棒性和快速的自适应能力, 为此提出采用自适应控制器方案, 该方案以线性二次调节器(linear quadratic regulator, LQR)比例积分型控制器作为稳定闭环, 在此基础上加入自适应控制器, 仿真结果表明, 采用自适应控制器的受油机自动空中加油飞行控制系统可以实现规定时间内的精确加油对接, 既满足瞬态性能要求, 又满足稳态精度要求, 同时, 还解决了由自适应参数跳动带来的舵机操纵过于频繁的问题. 该方法可有效提高对接过程中受油机飞行控制系统的抗干扰能力, 能够满足自动空中加油对接段的飞行控制要求. |
| 英文摘要 |
| During the automated aerial refueling (AAR), when the receiver approaches to couple with a refueling drogue, the hose-drogue system undergoes a transient motion due to the receiver forebody aerodynamic effect, in addition to the tanker motion and downwash. Thus, the receiver requires an accurate flight control. For this purpose, we propose a novel adaptive controller on the basis of LQR proportional integral control for stabilizing the closed-loop, to realize the fast accurate refueling with desirable transient performance and the steady-state precision. Simulation results show that this method ensures the realization of an accurate AAR in a given finite time period by restraining the disturbance as well as reducing the model error, and meets the control requirements of AAR in both the transient and steady states. |
