Fuzzy adaptive control for hypersonic vehicle via Backstepping method
基于Backstepping的高超声速飞行器模糊自适应控制

An adaptive fuzzy control strategy is proposed for the hypersonic aircraft. The dynamic inversion velocity controller and the Backstepping attitude controller are designed respectively based on the characteristics of the hypersonic vehicle model. The adaptive fuzzy system is then developed to identify the uncertain plant model in the presence of large variations in the aerodynamic parameters. The adaptation law designed by using Lyapunov theory guarantees the system stability and tracking accuracy. The longitudinal model of a hypersonic vehicle is used in demonstrating the effectiveness of the proposed strategy. Simulation results show the expected tracking performance.
