用于无人机精确着舰的翼伞归航控制方法

Homing Method of Controllable Parafoil for Landing of UAV on Deck

舰载无人机是未来的发展趋势,无人机如何能够精确安全着陆在小型舰船是亟需解决的关键技术。文章介绍了一种采用可控翼伞实现无人机精确着舰的回收方法,在传统的翼伞分段式归航控制方法的基础上,设计了一种带末段修正的改进型归航控制方法,有效提高了翼伞归航精度;再结合受控动目标协作控制方法,实现翼伞载无人机的精确着舰。文章建立了归航控制航迹规划模型,通过MATLAB软件进行了仿真分析,验证了控制方法的可行性,并与传统的分段归航控制方法进行比较,证明了该方法可显著提高着陆精度。

Carrier unmanned aerial vehicle （UAV） is a development trend in the future. Now how the UAV accurately and safely landing on a small ship is a key technology needed to be solved. This paper introduces a kind of method which UAV can accurately land on a small ship with a controllable parafoil. Based on the traditional multiphase homingmethod, it designs an improved control method with independent correction during the last phase, improving the accuracy effectively. Cooperated with the controllable moving target, parafoil with UAV can land on deck accurately. The paper builds a homing control pathplanning model, it carries out the simulation and analysis with MATLAB, and verifies the feasibility of this method. Comparing with the traditional homing method, this method can significantly improve the landing accuracy.
