基于多模态固定翼无人机下滑着陆控制设计与仿真

Design and simulation of sliding landing control for fixed-wing UAV based on multi-mode

无人机的飞行控制技术是关键技术之一,其主要分为飞行策略的建立以及核心控制技术两部分。飞行策略是在规划好飞行航线的同时控制其飞行过程的安全,而核心控制是保证无人机在运行中的稳定性。文章以某长航时大中型无人机为对象进行研究与设计,主要围绕无人机在自主飞行控制技术中的下滑与着陆过程,设计出下滑到着陆的导航航线并通过控制算法使无人机较好地跟踪下滑航线到着陆,实现了无人机下滑着陆阶段的精确性和安全性。最后,在MATLAB/Simulink环境下进行模块化的工程搭建以及下滑着陆段的设计与仿真。

The flight control technology of UAV is one of the key technologies,which is mainly divided into two parts:the establishment of flight strategy and core control technology.Flight strategy is to control the safety of the flight process while planning the flight route,and the core control is to ensure the stability of the UAV in operation.Based on the research and design of a long-endurance large and medium-sized UAV,this paper mainly focuses on the glide and landing process of the UAV in the autonomous flight control technology,designs the navigation route from glide to landing,and uses the control algorithm to make the UAV better track the glide path to landing,thus achieving the accuracy and safety of the UAV in the glide and landing stage.Finally,the modular engineering construction and the design and simulation of the glide landing section are carried out in MATLAB/Simulink environment.
