Multi-objective global optimal parafoil homing trajectory optimization via Gauss pseudospectral method

Based on a simplified parafoil model, this paper designs multi-objective global optimal homing trajectory of a parafoil by the Gauss pseudospectral method. Connecting with all constraint conditions, homing trajectories at different initial positions and heading angles are simulated. Simulation results show that the terminal error and flaredlanding angle error are small and that the control quantity is global optimal. The planned trajectory in horizontal plane is composed of arc and straight line, which accords with the features of parafoil completely.
