A useful dynamic analysis of hypersonic vehicle and control law design using uncertainty parameter dynamics model

Sections 1 through 4 of the full paper explain our dynamic analysis and control law design mentioned in the title; this explanation we believe is of reference value and whose core consists of: (1) the wide-range maneuver, rapid change of mass distribution, the complex aerodynamic characteristics and the mutual coupling of the structure, aerodynamics and thrust of a hypersonic vehicle contribute greatly to the strong uncertainty of its dynamics, which is a great challenge to the dynamic analysis and control law design; (2) we analyze the major uncertainty parameters which may contribute to the dynamics of the hypersonic vehicle; (3) we establish the uncertainty parameter dynamics model and analyze the impact of the uncertainty parameter changes on the hypersonic vehicle's eigenvalue distribution; (4) using the rigid-flexible body uncertainty model, we design the control law with the modified feedback linearization method. The simulation results, given in Table 1 and Figs. 2 through 4, provide a useful reference for a hypersonic vehicle's dynamics analysis, overall design and control law design.
