Study on Takeoff Control Design of Hypersonic Vehicle Based on Model Predictive Control

In this paper, the take-off control design problem for hypersonic vehicle(HSV) is studied. Firstly, the attitude dynamics model of HSV during take-off stage is established, and the model predictive control(MPC) approach is adopted for the attitude control of HSV. Furthermore, considering the influence of ground on airflow at low flight altitude, an improved model predictive control(IMPC) approach is presented by introducing the online parameter estimation of the ground influence coefficient for dealing with the uncertainty and disturbance. Finally, the efficiency and advantages of the proposed method are illustrated by the comparison simulation against traditional control design method.
