Adaptive higher order sliding mode attitude control for hypersonic glide vehicles

In this paper, a robust adaptive higher order sliding mode attitude control scheme is proposed for near space hypersonic glide vehicles. This problem can be viewed as the finite time stabilization of a higher order input-output dynamic system with bounded uncertainties. The control scheme developed is based on geometric homogeneity and dual layer adaptive sliding mode control. Simulation results show the effectiveness of the proposed controller to track the guidance instruction for the 6-DOF model of hypersonic reentry vehicles.
