导引和控制技术是大型无人机实现自动着陆的两项关键技术。针对分米波仪表着陆系统(DWILS)的无人机着陆导引与控制技术的仿真验证,为了提高导引的可靠性,给出了基于DWILS的无人机着陆地面仿真系统的结构,着陆导引仿真设备,根据DWILS的工作原理给出了导引信号的计算公式,同时设计了着陆控制器。根据导引设备的原理建立了基于DWILS的无人机着陆导引与控制仿真系统模型,并进行仿真验证。仿真结果表明,基于DWILS的导引方式满足无人机着陆导引的需要,设计的着陆控制器具有较好的控制效果。

Guidance and control are two key technologies of automatic landing for large UAVs.Decimeter wave instrument landing system（DWILS） is a method may be used in guidance for UAV during landing.How to testify the DWILS based landing guidance and control technologies in laboratory is studied in this paper.Firstly the architecture of a hardware-in-loop simulation system is given to testify the feasibility of DWILS for UAV landing guidance.Secondly,the simulator of guidance signal and calculation of guidance signal is described in detail.At the same time,the landing controller is designed.Then a model of landing simulation system guided by DWILS is established.Finally,simulation of UAV landing using DWILS is implemented.Simulation results show that DWILS can be used in landing guidance for UAV,and the landing controller has good performance.
