摘要
针对四旋翼飞行器无刷直流电机的特点,设计开发了无传感器调速控制系统。首先介绍了四旋翼飞行器的速度控制原理。对电机换相技术和反电势检测方法做了详细说明,并以MEGA8单片机为核心设计了外围硬件电路。最后通过实验进行了性能测试。
Based on the features of four-rotor and brushless DC motor, the sensorless speed-control system is designed. Firstly, the principle of the four-rotor speed-control is introduced. The phase-change of the motor and back EMF are explained in detail. The hardware circuit circumfused the MEGA8 singlechip is designed. At last, the capability is tested in experiment.
