Abstract :
This paper presents a nonlinear H∞ controller for the rejection of input disturbances in a fixed wing UAV. The proposed controller acts in all states of a complete nonlinear dynamic model. Simulation results show that the aircraft is successfully maintained in the desired stable condition after two different disturbances: a finite pulse and noise.
