平台与附件同时机动的复合控制技术是航天控制领域潜在的发展方向.分析了该技术的需求与研究内容,建立了该技术最简化的适用对象——两刚体对象的完整动力学方程,从问题复杂性、平台姿态描述、复合控制器设计用模型、系统耦合特征等角度展开讨论,并进行了系统控制器初步设计与仿真,得出关于模型建立、前馈策略、带宽选择等原则性意见.
Composite control of simultaneous maneuvers of a spacecraft platform and its appendages is potential research direction. Requirements and research contents are analyzed in this paper. Then, complete dynamics equation of a two-rigid-body system as a simplest object of the composite control is derived. Many topics are discussed, such as complexity of the problem, description of attitudes of the spacecraft platform, model simplifying for its composite controller and coupling characteristics of the system. The composite controller are designed for the system and numerical simulation done. Some principle advises about modeling, feedforward and bandwidth band choice strategies are given.
