A PSO Method for Trajectory Design of Boost Phase

This paper studies a trajectory design optimization method based on PSO (Particle Swarm Optimization) algorithm for rocket boost phase trajectory. The trajectory program of the active stage of the rocket was designed, and the PSO algorithm for the optimal design of the trajectory track was constructed. By designing the control parameter improvement strategy, the particle swarm iteration algorithm was improved. The analysis and simulation results show that the PSO algorithm can effectively solve the problem of solid rocket trajectory optimization design, optimize the trajectory path scheme in the boost phase to meet the separation point height, trajectory inclination and other constraints. The algorithm increases the convergent speed and stability. It is easy to engineering implementation and it can provide a theoretical reference for boost phase trajectory optimization design.
