Abstract：The parafoil system is a very unique class of flexible winged vehicle,due to the low speed characteristics,it is vulnerable to wind fields.Since it is difficulty for the parafoil system to track the desired homing trajectory precisely and achieve accurate landing in a large wind environment,the impacts of mean wind are taken into consideration in the stage of trajectory planning,and a multiphase homing trajectory is designed and optimized based on a modified particle swarm optimization (PSO) algorithm;in the meantime,the influences of turbulence are regarded as the external disturbances and amended by linear active disturbance rejection controllers (LADRC).Simulation results show that the proposed homing control strategy is of great importance to improve the homing accuracy and anti-wind ability for achieving set point homing of the parafoil system in large windy conditions.
