Integrated Guidance and Control Design of Wide-Area Hypersonic Vehicle Based on Dynamic Inversion

The hypersonic vehicles (HV) represented by the combined powered aerospace vehicle have the characteristics of strong coupling, uncertain aerodynamic parameters, and many control constraints during the ascent phase. The guidance system of HV couple with its trajectory control system strongly and the trajectory optimization and guidance system design process are interactive and complicated. In this paper, a three-dimensional integrated guidance and control algorithm based on dynamic inversion is proposed. The attitude loop controller and guidance controller are designed to establish a mapping relationship between the longitudinal and lateral channel commands and the control surface commands, height and lateral position control of HV can be controlled accurately. The simulation results show that the integrated guidance and control method of HV for the wide-area flight can track reference commands precisely.
