PID based controller design for attitude stabilization of Quad-rotor

Abstract

This article presents a PID based control approach for stabilizing the attitude of quad-rotor UAV during flying. To solve the stability problem of quad-rotor UAV, some suitable and easy feedback control algorithm can be used. In the standard Quad-rotor type UAV systems, controlling of attitude is one of the most critical tasks and appropriate controller for stabilization of attitude is essential and necessary. So, in order to validate the unwanted disturbance rejection operation, a robust PID controller with feedback compensation is derived in this research artical. The results proved the effectiveness of control method for stabilizing attitude of quad-rotor.
