A diving guidance method with terminal velocity constraint is proposed for the air-to-ground attack of the near-space hypersonic vehicle. Firstly, the motion of the hypersonic vehicle in the three-dimensional space is analyzed, and a two-stage guidance strategy is proposed. In both the longitudinal plane and the lateral plane, the control of terminal velocity is transformed into the adjustment of switching time between the two guidance stages. The switching time of the longitudinal guidance is obtained by an energy-based switching law, and the lateral switching time is adjusted according to the feedback of the velocity error. On this basis, a diving guidance method in the three-dimensional space is developed for the precision control of the terminal velocity. Finally, the proposed diving guidance method is verified by simulations in both nominal and dispersed cases. Results show that the diving guidance method with terminal velocity constraint can control the terminal velocity effectively while satisfying the terminal position and angle constraints.
