Design of landing attitude balance control system for fixed wing unmanned aerial vehicle for combat

摘要:

为解决当前控制系统存在对无人机落地高度测量误差大，落地各姿态角度大等问题，设计了作战用固定翼无人机落地姿态平衡控制系统。选用CMOS模拟多路复用器ADG508单芯片，对系统硬件电源电路、AD转换电路、信号采集电路、时钟复位电路、存储扩展电路及调试与接口电路进行优化，通过测量无人机落地姿态，完成系统软件设计，结合硬件与软件部分，实现作战用固定翼无人机落地姿态平衡控制系统的设计。实验结果表明，改进系统对无人机落地高度测量误差小，落地俯仰角、横滚角及偏航角小，具有较好的平衡控制效果，充分满足姿态测量需求。

Abstract:

In order to solve the problems such as low precision of aircraft landing attitude balance control and large range error, the landing attitude balance control system of fixed wing unmanned aerial vehicle for combat is designed. Using CMOS analog multiplexer ADG508 single chip, the hardware of the system power supply circuit, AD conversion circuit, signal acquisition circuit, clock reset circuit, memory expansion circuit and interface circuit debugging and optimization, through the measurement of UAV landing posture, complete the design of system software, combined with hardware and software, design and implementation of combat landing posture balance control the system with fixed wing uav. The experimental results show that the improved system has high control precision, fast return to steady attitude, fast measurement error and small height measurement error, which can fully meet the requirements of attitude measurement.
