In view of aircraft's nonlinear dynamics systems highly nonlinear, multivariable coupled and included uncertain parameters, a new inverse sliding mode controller was designed based on inverse design method and the variable structure control scheme. Sliding mode control was adopted in every inverse design to compensate for unmatched uncertainties and unknown disturbance. The approach prevents cumulative error and realizes robust output tracking to guide order. Tracking error is proved to converge to arbitrarily small area near origin. The simulation results show the effectiveness of this method.
