摘　　要：航天器着陆段通常存在落点散布大,低仰角测量时间长的特点,为提升着陆场系统对着陆段航天器的测控能力,设计了用于航天器着陆段测量的无人机测量集群,并提出了用于该集群控制的自组织控制方法.该方法将集群的运动控制分为3种行为规则,分别是集群初构型与待命行为、跟踪测量行为、集结回收行为;各行为规则下的个体控制通过比例组合多种人工势函数实现.详细介绍了各行为规则下控制力的构成及基础人工势函数的设计方案,通过仿真计算验证了该集群自组织控制方法的有效性.In order to improve the measurement and control capability of field system for reentry spacecraft’s landing section,a UAV measurement cluster for this task and a cluster self-organizing control method are designed.This method is divided into three behavior rules:initial configuration and standby behavior,tracking behavior and collection and recovery behavior.The individual control under each behavior rule is achieved by proportionally combining multiple artificial potential functions,the composition of the control force under each behavior rule and the design scheme of basic artificial potential function are introduced in detail.Experiments confirmed the effectiveness of this control method.
