Abstract:

For the control problem of hypersonic vehicle with angle of attack (AOA) constraint, a backstepping control scheme combining constrained command filter and prescribed performance method is proposed. Firstly, the altitude subsystem is divided from the hypersonic vehicle motion model and the controller is designed based on the backstepping control method. In order to solve the problem of AOA constraint, a constrained command filter is constructed to limit the virtual command of AOA and ensure the virtual command's differentiability. Then, the constraint range is set in advance by using the prescribed performance method to ensure that the tracking error of AOA meets the constraint condition and to improve its transient and steady performance. In addition, linear extended state observer (LESO) is used to observe and compensate the parameter uncertainties of the system and external disturbances. Based on Lyapunov stability theory, it is proved that the tracking error of the system is uniformly bounded. Finally, the simulation results show that the proposed method is effectiveness.

Key words: hypersonic vehicle, angle of attack (AOA) constraint, command filter, prescribed performance, linear extended state observer
