摘要：
A midcourse flight trajectory planning algorithm based on receding sequential convex programming algorithm is proposed for a long-range flight vehicle to strike low-speed ship target. Using a receding planning framework, the trajectory update problem is transformed into a trajectory planning subproblem after initial and terminal position updates. Then, a multi-constraint convex optimization problem is constructed and solved using sequential convex programming algorithm. A receding planning cycle contraction strategy is designed to reduce the number of trajectory updates. An improved reference trajectory generation algorithm is designed and a trust region adaptive shrinkage strategy is used to effectively improve the computational speed while ensuring the planning effect. Simulation results show that the algorithm has fine planning results and can meet the online planning requirements. The computational speed is faster compared with usual receding sequential convex programming trajectory planning algorithms. © 2024 Chinese Institute of Electronics. All rights reserved.
