摘要
This paper discusses the novel anti-disturbance control algorithm for hypersonic flight vehicle(HFV) models by using neural network(NN) identifier. Different from those existed anti-disturbance results, the unknown exogenous disturbances in HFV models are assumed to be described by the designed NNs with adjustable parameters. Furthermore, the disturbanceobserver-based-control(DOBC) algorithm with adaptive regulation laws is thus presented to estimate the nonlinear disturbances.By integrating the estimated value of disturbances with the PI feedback control input, a composite controller based on convex optimization theory is generated to ensure the satisfactory stability and dynamical tacking convergence of HFV models. Finally,a numerical example for HFV models is included to illustrate the effectiveness of the theoretical results.
