| Abstract: | Parafoil recovery system has the characteristics of accuracy,fixed-point and non-destruction,and has become a research hot-spot in the current recycling areas.Firstly,a six-degree-of-freedom dynamic model of parafoil system with additional mass was established.Then,it was brought into the kinetic equation to obtain the time curves of trajectory,and three attitude angles varied with different control modes.Secondly,the trajectory planning of parafoil system was designed by using multiphase homing strategy and the parameters were solved iteratively by genetic algorithm.Finally,comparing the new multiphase homing project with the traditional multiphase homing project,the simulation results show that the new multiphase homing strategy performs better in energy control and stability. |
