Adaptive backstepping controller design for hypersonic vehicles

A novel nonlinear control scheme based on backstepping and nonlinear dynamic inversion methods for the hypersonic vehicles is presented here. The MIMO strongly coupled system is accurately linearized using the dynamic inversion method. The system global stability is guaranteed by the baskstepping control method, which tracks the command signals accurately. The effects of the uncertain parameters is attenuated using the fuzzy observer. The simulation results show that the scheme solves the uncertainties brought by the actual flight of the vehicles.
