Abstract

In order to realize safe and accurate homing of parafoil system a multiphase homing trajectory planning scheme is proposed according to the maneuverability and basic flight characteristics of the vehicle In this scenario on the basis of geometric relationship of each phase trajectory the problem of trajectory planning is transformed to parameter optimizing and then auxiliary populationbased quantum differential evolution algorithm APQDEA is applied as a tool to optimize the objective function and the design parameters of the whole homing trajectory are obtained The proposed APQDEA combines the strengths of differential evolution algorithm DEA and quantum evolution algorithm QEA and the notion of auxiliary population is introduced into the proposed algorithm to improve the searching precision and speed The simulation results show that the proposed APQDEA is proven its superior in both effectiveness and efficiency by solving a set of benchmark problems and the multiphase homing scheme can fulfill the requirement of fixedpoints and upwind landing in the process of homing which is simple in control and facile in practice as wellFoundation item Project61273138 supported by the National Natural Science Foundation of China ProjectsKJ2016A169 KJ2015A242 supported by the University Natural Science Research Key Project of Anhui Province China ProjectZRC2014444 supported by the Talents Program of Anhui Science and Technology University China
