Summary:Aerodynamic parameters identification is a key enabling technology to improve the adaptivity of the guidance and control for hypersonic gliding vehicle. This paper seeks to propose a novel online aerodynamic parameters identification scheme under the framework of nonlinear observer. Firstly, the original nonlinear dynamics for the air-to-ground attack of the hypersonic vehicle is established, while the lumped aerodynamic forces are regarded as the external terms. Then, a nonlinear observer is employed to estimate the lumped aerodynamic forces, and the ultimate boundedness of the estimation error is guaranteed with Lyapunov theory. Finally, simulation results are undertaken to show the effectiveness of the proposed scheme.
