Concise Neural Nonaffine Control of Air-Breathing Hypersonic Vehicles Subject to Parametric Uncertainties

Blog Article

In this paper, a novel simplified neural control strategy is proposed for the longitudinal dynamics of an air-breathing hypersonic vehicle (AHV) directly using nonaffine models instead of affine ones.For the velocity dynamics, an adaptive neural controller is devised based on a minimal-learning parameter (MLP) technique for the sake of decreasing computational loads.The altitude dynamics is rewritten as a pure feedback nonaffine michael harris sunglasses formulation, for which a novel concise neural control approach is achieved without backstepping.

The special contributions are that the control architecture is concise and the computational cost is low.Moreover, the exploited controller possesses good practicability since there is no need for affine models.The semiglobally uniformly ultimate boundedness of jilungin dreaming tea all the closed-loop system signals is guaranteed via Lyapunov stability theory.

Finally, simulation results are presented to validate the effectiveness of the investigated control methodology in the presence of parametric uncertainties.
