[0080] Example 1:
[0081]Step 1: Considering the flight state constraints, the influence of input saturation, the additional disturbances generated by the continuous deformation process, and the uncertainty of aerodynamic parameters, the longitudinal dynamics model of the hypersonic variable-sweep wing aircraft is established.
[0082] Taking the aerodynamic and structural data of the Variable-sweep-wing Morphing Waverider (VMW) as an example, the longitudinal dynamic model is established as follows:
[0083]
[0084] Among them, H is the flight height, X is the forward flight distance, V is the flight speed, γ is the ballistic inclination angle, θ is the pitch angle of the body, α is the flight angle of attack, q is the pitch angular velocity, and Λ is the wing sweep angle. The total mass of the aircraft is m=600kg, is the moment of inertia of the body to the body's center of mass, is the moment of inertia of the wing to the center of mass of the body, specifically: ...
