基于STM32的无人机飞行器设计

The design of unmanned aerial vehicle based on STM32

四旋翼无人机由于体积小、结构简单、运行灵活、成本低等优势在无人机市场占据一定地位。针对无人机的飞行控制系统进行电路设计,以STM32F103C8T6作为核心控制板,采用MPU6050作为姿态传感器,结合HMC5883L磁罗盘传感器,无线数据通信使用SX1278模块,增加无人机和手机之间的蓝牙通信功能,通过PWM调速控制四路电机旋转,主要功能实现自动维持无人机的正常飞行姿态。

Quad-rotor UAV occupies a certain position in the UAV market because of its small size, simple structure, flexible operation, low cost and other advantages. The flight control system of UAV is designed with STM32F103C8T6 as the core control board, MPU6050 as the attitude sensor, HMC5883 L magnetic compass sensor, SX1278 module for wireless data communication, Bluetooth communication between UAV and mobile phone is added, and four motors are controlled by PWM speed regulation. The main function is to maintain the normal flight attitude of UAV automatically.
