无人机自动空中加油精确对接控制

摘要

The control scheme and strategy for unmanned aircraft vehicle automated aerial refueling were proposed based on analysis of the vortex effect of tank and the free oscillation of drogue.The improved reference trajectory generator and trajectory tracking controller for receiver were used for automated aerial refueling precise docking control.The linear quadratic regulator method was used to design the trajectory tracking controller,and all kinds of disturbance were considered.The results of simulation show this guidance control method has the capacity for speeding up system response and restraining disturbance;Furthermore,it meets the requirement of automated aerial refueling.%针对无人机自动空中加油对接段的精确控制问题,提出了无人机自动空中加油的控制方案和策略,并在分析加油机尾涡干扰和加油锥套自由摆动及其对受油机影响的基础上,设计了适用于自动空中加油精确对接控制的受油机参考轨迹发生器和轨迹跟踪控制器.轨迹跟踪控制器采用线性二次型调节器方法,并充分考虑了加油过程中各种干扰的影响.仿真结果表明,该导引控制方法具有良好的快速性和抗干扰能力,可以满足空中加油的任务要求.
