Design of Motor Drive System for Four Rotor Unmanned Aerial Vehicle

摘要

The motor drive system is a servo mechanism to control the four rotor UAV (unmanned aerial vehicle) system, and it is also a key component to control the attitude and trajectory of UAV. Its performance directly affects the performance and safety of the flight control system. The working principle of the system is that the motor drive control signal can receive output of flight control computer and convert into current signal to coordinate control of four motor speed, thus the attitude and action of four rotor UAV flight are changed, and the mission set by the operator is completed to control the smooth flight of UAV.
