摘要
设计是以ST公司的STM32F103ZET6为控制芯片,通过I2 C实现它与气压高度传感器、三轴加速度计、三轴数字罗盘及三轴陀螺仪之间的数据、指令传输,再利用电机驱动电路和芯片内部的定时器产生PWM波来共同控制2个机翼上电机的转速,最后通过GSM模块将飞行数据传回地面,这就组成了一个飞控系统。实验表明,该飞控系统具有耗能低、稳定性好以及集成度高等优点,而且能使飞机沿着预设的轨道飞行。
The design uses the ST STM32F103ZET6 as the core chip.By using the I2C serial bus,the purpose of the transmission of data and instructions between the chip with barometric altitude sensor,three-axis digital accelerometer,three-axis digital compass,three-axis gyroscope could be realized.The speed of the motor under the two wings was controlled by the motor drive circuit and the PWM generated by the internal timer,final flight data was transmitted to the ground through the GSM module,thereby this constituted a flight control system.The experiment showed that the system designed had low power consumption,good stability and high integration,and made the flight fly along the pre-designed orbit.
