Algorithm Four-rotor UAV Attitude From The Control
Abstract: The Four-rotor wing aircraft is the object in the paper. As its flight attitude is hard to reach self-stabilization, the attitude stabilization algorithm is proposed and tested. The Px4 is the control core of the flight system, and the Kalmar filter can compensate the data in the Hardware. The sensor circuit and the Non reversing motor are designed which coincide with the controller. Its flight Attitude can achieve the real-time stability. The data is obtained using MATLAB simulation in the paper. What’s more, the Four-rotor Unmanned Aerial Vehicle (UAV) is designed. Finally, it
can fly successful and to its flight attitude achieve the real-time stability.
