| 摘 要： | 归航轨迹的设计和优化对实现翼伞系统的精确空投至关重要.为了实现翼伞系统的准确、安全着陆,根据翼伞系统自身的可操纵性和基本运动特性,采用经典分段归航策略.利用各段轨迹的几何关系将轨迹优化问题转化为参数优化问题,并对基本遗传算法进行了改进,运用新的改进自适应遗传算法(IAGA)进行了有效的求解.仿真试验表明:此方法是可行的...

| Abstract: | Design and optimization of homing trajectory is essential for accurate aerial delivery of parafoil system.In order to realize accurate and safe landing of parafoil system,classic multiphase homing trajectory was adopted according to the maneuverability and basic flight characters of the parafoil itself.The trajectory optimization issue was transformed into a parameter optimization issue by use of the geometric relationship between each trajectory.Then the basic genetic algorithm was improved,and an effectiv... |
