Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a simulation test platform for hypersonic aircraft assessment and a control method thereof. Background technique [0002] At present, hypersonic vehicles are highly forward-looking, strategic and driving, and have shown great development potential in both military and civilian aspects, so they have become a hot spot for research and development in various countries. Compared with conventional aircraft, hypersonic aircraft adopts a unique fuselage-engine integrated design, which leads to complex characteristics such as strong nonlinearity, strong coupling, and fast time-varying during flight, making hypersonic aircraft in the evaluation of performance It is difficult to make a reasonable comparison. [0003] However, the current control methods of hypersonic vehicles have the characteristics of fast time-varying, strong coupling, and strong nonlinear behavior, and it...
