基于进场雷达引导的无人机自主着陆控制规律设计与仿真

UAV Autonomous Landing Control Law Design and Simulation based on Approach Guiding Radar

为了实现无人机在进场雷达引导下按照预定的航迹自主着陆,进场雷达会实时测量无人机的航迹并和预定航迹比较产生偏差引导信号发送给无人机,无人机在引导信号作用下通过控制系统不断的调整舵面,来改变其所受到的气动力和气动力矩,实现对着陆姿态和航迹的自主控制。在仿真中采用基于Matlab/Simulink的无人机六自由度非线性数学模型,设计了高度稳定与姿态控制回路,通过对仿真结果的分析,验证了飞行控制系统设计的合理性,实现了无人机按照预定航迹的自主着陆仿真。

In order to achieve the UAV autonomous landing under the approach radar according to a predetermined track, approach radar will measure UAV＇ s track all times and compare the intend track and send the deviations signal to UAV, Control system under the guidance signal continuously adjusts the rudder to change its aerodynamic forces and moments, achieve independent control of the landing attitude and flight path. In this paper, the simulation uses of six degrees of freedom nonlinear mathematical model of UAV Matlab / Simulink-based, high stable and attitude stable control loop were designed, through the analysis of simulation results the flight control system design is verified reasonable, autonomous landing UAV simulation in accordance with a predetermined flighting road was achieved.
