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

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.
