Fixed-wing UAV Recovery Reliably by Moving Platforms based on Differential Games

This paper studies the guidance and control problem of fixed-wing UAV landing on the ground moving platform. Although many studies should be conducted on the problem of helicopter or quadrotor landing on the mobile platform, but it's always been a challenge of recovering a fixed- wing UAV because of the high speed of UAV and the uncertainty of the motion of the ground moving platform. In this paper, an algorithm of UAV recovery based on differential game method is proposed. With the linear kinematics equation of UAV, the optimal evasion control of ground moving platform is regarded as the worst situation faced by UAV in the process of UAV recovery. The simulation results show that the proposed method can successfully accomplish the UAV recovery task in the worst dynamic environment.
