This paper proposes the control strategy based on the theory of predefined time stability for the formation of hypersonic gliding vehicles. First, we establish a six-degree-of-freedom integrated guidance and control model for the hypersonic glider vehicle, and simplify the model based on the inversion structure. Then, we design a predefined time control law to achieve formation control and maintenance. We also use artificial potential field theory to design a collision avoidance potential field function to prevent collision between the hypersonic glide vehicle and neighboring aircraft, and to avoid threat zones. Additionally, using Lyapunov stability theory, we strictly prove the stability of the formation states of the hypersonic glide vehicle within a predefined time. Finally, the simulation was conducted using Matlab/Simulink. The results demonstrate that the control method designed in this paper can achieve formation generation and maintenance, as well as implement collision avoidance and threat zone avoidance for hypersonic glide vehicles within the predefined time.
