It is our objective to research the nonlinear control dififcult problem of the air-breathing aerospace plane with strong coupling between aerodynamics, propulsion, and structure. First, the analysis was done to understand the reason of resulting in those strong coupling and the dififculty of lfight control. Second, it was analyzed how several advanced control theory methods were applied to the air-breathing aerospace plane. Third, the method of designing two controllers based respectively on high-order sliding mode and robust-adaptive was explored for the air-breathing aerospace plane, and the primary idea of two controllers was embodied. Finally, the potential of two controllers was evaluated.
