Abstract—The purpose of this paper consists of developing a robust control law for a fixed wing Unmanned Aerial Vehicle (UAV). To reach such a goal, a homogeneous continuous super twisting algorithm is used to solve the problem of attitude control for an aircraft model known by its nonlinearity and its strong coupling. Being a class of high order sliding mode (HOSM) control, super twisting algorithm (STW) allows finite time output convergence and chattering minimization for systems having relative degree equal to one. Hence, the use of homogeneity that allows the implementation of HOSM to control systems that have relative degree greater than one. Simulation results are shown to demonstrate the robustness of the proposed controller.

Index Terms—Fixed-wing UAVs, homogeneous control, sliding mode control law, super twisting, stabilization.
