Design of Attitude Control System for Four Rotor UAV

[摘要] This paper designs the quadrotor aircraft, and the software algorithm is the core. The software structure mainly uses the quaternion to Euler angle algorithm as the core to carry out the real-time attitude calculation of the aircraft, and supplemented by the cascade PID controller algorithm to stabilize, accurately and quickly respond to the RF signal. In this paper, the final goal of stable flight is achieved by solving the flight attitude algorithm.
