| Abstract: | According to the dynamic equations of parafoil system,the 6-DOF motion model established is presented.The flare-landing process of parafoil system is simulated to analyze the effect of control method applied to the performance of flare-landing.Under the special circumstance in the phases of the landing of homing process,PID controller is designed to correct the deviations due to the vertical error which is generated in the process of trajectory tracking.The simulation results show that the designed controller can eliminate the vertical errors simply and effectively and ensures the smooth flare-landing maneuver. |
