Multiphase Homing Track Planing for Parafoil-Booster Using Improved PSO Algorithm

This paper addresses a problem of designing an algorithm to find optimal trajectory when parafoil-booster system homing to desires point. Firstly, based on the theory of parafoil and path planning, the model of parafoil mounted on space booster is modeled, the homing track is calculated by stages, the objective function is established, and the weight coefficient is introduced. At the same time, the optimal path is planned considering the fall point error and energy loss. Secondly, aiming at the shortcomings of Particle Swarm optimization (PSO) algorithm in path planning, Beetle Antennae Search (BAS) is introduced to improve it, and the simulation experiments are carried out respectively.
