摘 要:A novel adaptive neural control strategy is exploited for the longitudinal dynamics of a generic flexible air-breathing hypersonic vehicle(FAHV).By utilizing functional decomposition method, the dynamics of FAHV is decomposed into the velocity subsystem and the altitude *** each subsystem, only one neural network is employed for the unknown function *** further reduce the computational burden, minimal-learning parameter(MLP)technology is used to estimate the norm of ideal weight vectors rather than their *** introducing sliding mode differentiator(SMD) to estimate the newly defined variables, there is no need for the strict-feedback form and virtual *** the developed control law is considerably simpler than the ones derived from back-stepping ***, simulation studies are made to illustrate the effectiveness of the proposed control approach in spite of the flexible effects, system uncertainties and varying disturbances.
