空中加油受油机自主会合对接控制器设计

为了实现受油机与加油机自主会合对接,提高在会合对接过程中的航迹跟踪性能,设计了一种满足位置跟踪与速度跟踪的制导律,推导了相应的飞控指令。在飞控系统设计上,按六自由度受油机动力学模型,采用时标分离将受油机角运动系统分为快慢回路,采用动态逆分别进行了设计。同样,采用动态逆的方法设计了满足会合对接的速度控制律。最后以无人机自主跟踪加油机实现会合对接为例进行了仿真,结果表明该系统能够引导受油机实现与加油机的会合对接,并具有良好的动态性能。

Guidance and control of autonomous aerial refueling rendezvous and docking

In order to improve the performance of aerial refueling rendezvous and docking, A guidance algorithm is designed to satisfy the tracking of position and velocity. In flight control loop, based on the 6-DOF model, the angular rate loop and the attitude loop are separated based on time-scale and the control law is designed using dynamic inversion. Nonlinear digital simulation results demonstrate that the controller is capable of guidance the receiver rendezvous with the tanker, and has good transient performance.
