This article investigates the design of an autopilot for flight control of a planar vertical take-Off and landing (PVTOL) aircraft to maintain the airplane on the desired flight path. This UAV is a nonlinear and non-minimum phase system and may face external disturbances (such as wind and …) in their flight path. Thus designing a controller with a robust manner to achieve desirable flight performances (in the present of external disturbances or model uncertainties) is an essential issue. For this purpose; in this paper the dynamic sliding mode technique is applied. This method is a robust technique for stabilization of uncertain non-linear systems which has better performance in comparison with the classical sliding-mode method. The robust autopilot controller is designed by use of the mentioned method such that the UAV flies in the specified desired path (determined based on its mission). Finally, computer simulations indicate the effectiveness of the proposed controller.
