Abstract

Hypersonic vehicle (HSV) has strong nonlinearity, high coupling and multiple variables in the reentry process, bringing challenges for the attitude controller design. This paper investigates a compound control scheme combined with the advantages of the linear quadratic regulator (LQR) and active disturbance rejection control (ADRC) method for the reentry flight attitude control of HSV. Firstly, the HSV 6-degree-of-freedom model is established. Then the LQR control method is used for the reentry attitude control of the HSV. After that, the basic active disturbance rejection control (ADRC) method is built, and the extended state observer (ESO) is designed to make compensation for the uncertainty of the model. The LQRADRC method for the HSV is firstly proposed. Finally, the simulation results are shown to illustrate the advantages of the proposed LQRADRC method in terms of accuracy and robustness with uncertain parameters.
