Abstract: A dynamic inversion control method based on variable structure theory is presented according to the feature that hypersonic vehicle model is highly nonlinear,strong coupled and includes uncertain parameters.This method combines the non-linear decoupling ability of inversion control with the strong robustness of variable structure theory very well.So it can ensure the longitudinal flight stability and improve the control performance of hypersonic vehicle.Simulation studies demonstrate that the control method is feasible for hypersonic vehicle.
