Predefined-time based Tracking and Formation Control for Hypersonic Flight Vehicles

In this paper, the hypersonic flight vehicle(HFV) is taken as the research object. The problems of tracking control and formation control are studied. A predefined time control method is proposed to ensure the stability of the system in the expected time. Considering the complexity of the model, firstly, the hypersonic flight vehicle model is decoupled. Secondly, the desired value tracking control is realized for a single HFV. Next, on the basis, it is extended to multiple HFVs system to realize formation control. Then, the stability is proved according to Lyapunov stability theory. Finally, the effectiveness of the proposed control methods is verified by simulation results.
