| 摘 要： | 针对翼伞系统的基本飞行特性和良好的可操纵性,采用分段设计的思想对翼伞系统的归航轨迹进行规划.根据各分段轨迹之间的几何关系,将航迹规划问题转变为对设计参数的寻优问题.实际系统所能提供的能量是有限的.因此,在目标函数中加入控制能量的约束.运用改进的粒子群算法对目标函数进行求解计算,得到整个归航轨迹的设计参数.仿真结果表明:...

| Abstract: | According to the basic flight characteristics and good controllability of parafoil system,the theory of multiphase design is used to plan the homing trajectory of parafoil system.The problem of trajectory planning is transformed to parameter optimizing on the basis of geometric relation of each phase trajectory.Due to the limitation of energy which is provided by system in practice,the energy confinement is added to the objective function.By applying a modified particle swarm optimization algorithm to calcu... |
