Description

technical field [0001] The invention relates to the field of aircraft control, in particular to an expert intelligent control method for a hypersonic aircraft and the aircraft. Background technique [0002] Hypersonic deformable aircraft is a special type of hypersonic aircraft, whose main feature is that it can actively change its shape and structure according to the requirements of the flight environment and flight missions, so as to obtain better aerodynamic characteristics and maneuverability, and achieve wide range with less energy consumption. High speed and wide airspace flight. The hypersonic deformable aircraft takes the shape parameters as controllable variables, and uses the influence of the shape parameters on the aerodynamic characteristics to change the performance of the aircraft, so that it can adapt to a wider range of flight airspace and speed domain, so that it can adapt to more complex flight tasks and flight environment. At the same time, the hypersoni...

Problems solved by technology

However, in the current control methods for deformable aircraft, the parameter selection of the controller is usually a set of fixed parameters selected in advance, which brings about the problem that for hypersonic deformable aircraft, a set of controller parameters is difficult to adapt The deformation process of the aircraft and the severe aerodynamic changes at hypersonic speeds make it difficult to obtain the optimal control effect for the motion control of the aircraft
