One near space hypersonic aircraft attack angle observer and controller design

A novel sliding surface observer and controller is designed based on Lyapunov function for hypersonic aircraft nonlinear dynamitic system. Overload output sliding surface to construct Lyapunov function to guarantee the astringency of observer. Dynamic surface adaptive backstepping is adopted designed to ensure control law, and multi-layers neural network adjust function is used to compensate the influence from the uncertain, which designs the robust terms to solve the problem from approach error. The stability analysis and simulations demonstrate the good performance of the controller.
