Automated carrier landing of an Unmanned Air Vehicle is a complex process.To successfully complete the task of landing on carrier,firstly the guidance system should give UAV flight control system a proper landing trajectory,then the flight control system according to the instructions given by the guidance system of UAV make the UAV fly on the right track,finally realizing automatic landing on carrier.In this process the guidance system providing correct guidance signal is a key factor in the success of landing on carrier.Now most aircraft carriers have angled deck,so there are great differences to ground-based landing.In view of this situation,a guidance law is designed for UAV landing on carrier,and the simulation of guidance law is carried out.Because of the air flow disturbance behind of the carrier,the requirement of flight control system is robust,so,this paper introduces quantitative feedback robust control design method to design the flight controller,in order to guarantee the robustness of control system.The results show that the guidance law and flight control system designed in this paper could realize the UAV autonomous landing.
