Abstract

In this paper, a robust nonlinear dynamic inversion (NDI) control law is proposed for the attitude tracking of the unpowered flying vehicle, which is a highly nonlinear strong coupled and time-varying system. Furthermore uncertainties such as inertia uncertainty and aerodynamic moment uncertainty are taken into consideration. Then the modified proportional navigation guidance (PNG) law is derived, which is based on the sliding mode control theory. Finally we demonstrate the validity of the proposed control law and guidance law by six-degree-of-freedom (6-DOF) simulation.
