This paper proposes a control design strategyencompassing trajectory tracking and path following for acategory of convertible aircraft with fixed wings and vectorizedthrust as exemplified by the Harri

The control design strategy proposed in this paper is aimed at a specific category of aircraft that have fixed wings and vectorized thrust, such as the Harrier jet aircraft and the V-22 Osprey. The strategy builds upon previous works on the control of other types of vehicles, including hovering vehicles, axisymmetric devices, and fixed-wing aircraft.

The proposed solution is based on a non-linear model of aerodynamic forces that is both simple and representative of the underlying physics. This model is used to develop a control system that can handle the delicate transition problem between hovering and cruising flight, which involves the tilting of the aircraft's thrust. The proposed strategy enables the continuous minimization of thrust intensity, which leads to a reduction in energy expenditure.

Overall, the proposed control design strategy offers a unifying approach to the control of convertible aircraft with fixed wings and vectorized thrust. It addresses the unique challenges associated with these types of aircraft, such as the transition between hovering and cruising flight, and provides a solution that is both effective and efficient
