小型无人机飞行控制系统设计及验证

Design and Test for Flight Control System Based on Small UAV

为提高小型无人机的自主飞行能力,对全流程自主飞行控制系统的设计进行研究。以某小型固定翼无人机作为研究平台,设计控制系统及制导系统,在航迹跟踪控制模态中引入侧向偏离速度量,并进行试飞场景设计及试飞验证。结果表明:该系统能提高航迹跟踪的快速性和精度,其控制律及制导率是正确、实用的,在提升无人机自主控制等级的同时能为自主编队控制等相关技术做好前期准备工作。

All processes of autonomous control are designed for improving the ability of autonomous flight on the small unmanned air vehicle. The research is based on the certain type small fixed-wing unmanned air vehicle in this paper. Firstly, flight control system and guidance laws are promoted, then the velocity of lateral departure from desired flight path was used in tracking flight path mode, at last the flight scene was designed for flight test. The results show that the system could raise the speed and precision in tracking flight path, and control laws and guidance laws are correct and practical. It not only upgrades the degree of autonomous control, but also be prepared for autonomous formation control and the other concerned technologies.
