For the characters of nonlinearity, multivariable and parameter uncertainty of hypersonic vehicle model, and the
possible singularity phenomenon of the controller resulted from changing of control gain, a fuzzy adaptive nonlinear control
approach based on dynamic surface control(DSC) is proposed. The altitude and velocity tracking controllers are designed
by using DSC and dynamic inversion strategies respectively. The fuzzy adaptive method is used to identify the uncertain
function terms on-line. The Nussbaum gain approach is adopted to restrain the influence caused by the uncertain virtual
control gain and decrease the burden of on-line learning. The controlled systems are ensured to be semi-global uniformly
ultimately bounded. The simulation results show that the accurate tracking control of hypersonic vehicle about altitude and
velocity can be realized by using the proposed approach.
