Tailless aircraft trajectory tracking control method based on non-affine model

The invention discloses a supersonic-speed tailless aircraft trajectory tracking control method based on a non-affine model, which aims at solving the problem of STAV trajectory tracking control with model non-affine characteristics, model uncertainty and external interference, and comprises the following steps: firstly, providing a new non-affine model pseudo-affine conversion method, carrying out pseudo-affine conversion on the non-affine model, and carrying out pseudo-affine conversion on the non-affine model; a non-simulation system self-adaptive controller is designed; secondly, for the trajectory tracking control problem, the STAV dynamic model is decomposed into a translation subsystem, a rotation subsystem and a torque distribution module; the outer ring subsystem is used for designing a sliding mode controller based on an error surface, the inner ring subsystem is used for designing an adaptive controller based on NDI, and an aerodynamic rudder and vector thrust composite control distribution law is
