Abstract

A two-stage cooperative trajectory fast planning method based on pseudo-spectral method and sequence convex optimization is proposed for the cooperative guidance problem of hypersonic gliding vehicle. First, a hypersonic gliding vehicle dynamics and kinematics model is established. Secondly, considering multiple path constraints and terminal constraints in the re-entry gliding section, the pseudo-spectral method is used to solve the complex kinematic model of the vehicle offline, and trajectories that satisfy the relevant cooperative indexes are obtained. Then, on the basis of the offline optimized trajectories, an improved sequential convex optimization algorithm is adopted to adaptively update the radius of the trust region, which improves the convergence speed of the algorithm and realizes the rapid planning of the synergistic trajectories under the premise of guaranteeing the accuracy of the solution. Finally, the proposed method is verified by mathematical simulation, and the results show that the method can realize cooperative flight under the state of uncertainty of the initial conditions and model of the vehicle, and the time cooperative error is less than 0.5 s, and the average CPU time of a single trajectory optimization is 3.67 s, which has a good potential for engineering application.

Key words： hypersonic gliding vehicle; sequential convex optimization; cooperative trajectory planning; trust-region
