Small Unmanned Reconnaissance Aircraft Flight Control System Real-time Software Design And Flight Test Research

The short range unmanned reconnaissance aircraft primary equipment the combat unit, which is used to carry out the tactical reconnaissance and the war zone contact mission. It is an important constituent of modernization weaponry construction.UAV flight control system is the core part of UAV. UAV flight control system design has the cross discipline and highly comprehensive characteristic. This article mainly has discussed the modern UAV flight control system design technology from UAV flight control system design technology comprehensive angle, mainly involves to the computer application, the automatic control, the wireless communication, the electromagnetic compatibility technology and many kinds of disciplines. According to the technical method which discussed has completed the unmanned reconnaissance aircraft control system hardware and the software development, and it has realized the basic function in modern UAV control system.This paper has carried on the brief introduction to UAV related knowledge at first, then discussed to the flight control and the flight management' s function, and then acts according to wind tunnel data of UAV to carry on the control law design. At the same time we analyzed with the software and hardware platform, has carried on the detailed introduction to task management software of UAV. Finally carries on the introduction to the UAV hardware-in-loop simulation system, at the same time we analysis the problem which happened in experiment according to the test flight, and discovered where the question in and gives the test flight to confirm.
