Research on Adaptive Guidance Technology of UAV Ship Landing System Based on Net Recovery

Abstract According to the characteristics of the target ship in motion in the net recovery process of UAV, this paper put forward the guidance law based on angle of sight by taking missile guidance law of proportional guidance law for reference, and introduced the backstepping guidance law to improve the adaptability of guidance law. Since the angle of sight guidance law is to make the UAV flight path angle and angle of sight be proportional to the rate of change, flight path angle can be tracked by controlling the angle of sight. That taking the guidance law into use can reduce the sensitivity of UAV motion on the ship parameters change, thereby to obtain more stable trajectory. The simulation shows the feasibility of this guidance law, and has strong robustness.
