Analysis Of Autopilot System Based On Bank Angle Of Small Uav
This paper present the autopilot control for unmanned aerial vehicle (UAV) flight system. The main contribution of this work is to control the bank angle of an airplane using differential deflections of the ailerons. Firstly, the steady-state flight conditions have to be accomplished. Secondly, we have to regulate the airplane bank angle to zero degrees and maintain the wings-level orientation in the presence of unpredictable external disturbances. Finally, we have to control the airplane bank angle for attitude control of an airplane. The mathematical implementation for second order approximation and third order approximation with different controller gain has been analyzed in this paper. The simulation results show the performance specification of the UAV system in autopilot mode.
