摘要：In the text of Wolf Totem, there are many spots of indeterminacy left purposely or involuntarily by the author in the depiction of characters, scenes, events and in the use of culture-related expressions, which are to be filled in by individual＇s interpretation through active reading of the work. Howard Goldblatt, as the translator of this work, adopts ＂creative rewriting＂ in the translation of Wolf Totem to actualize the indeterminacy and the factors guiding his concretization.

摘要：针对多航天器系统的姿态协同控制问题,基于特殊正交群(Special Orthogonal Group,SO(3))提出了滑模协同控制设计方法。结合有向通信拓扑,建立了多航天器SO(3)姿态模型。在此基础上研究了SO(3)上协同误差形式,提出了适用于协同控制器构造的SO(3)指令设计方法。为了解决姿态奇异问题,根据SO(3)姿态特性引入补偿项并设计了相应的滑模面,进一步采用反步法完成了SO(3)协同控制器设计,同时给出稳定性分析过程。提出的反步滑模方法保证了协同控制器在整个姿态空间内的适用性,使得多航天器系统能够实现稳定的姿态协同。文中采用两组多航天器系统仿真校验了所提协同方法的有效性。

摘要：针对多四旋翼无人机系统的编队飞行问题,提出了基于特殊正交群SO(3)的协同控制设计方法.在给出编队空间队形和通信拓扑描述后,建立了多四旋翼无人机系统SO(3)控制模型.由于SO(3)与传统俯仰/偏航/滚转三通道模型具有不同的结构,文中进一步研究了SO(3)中无人机之间相对误差的表示方法,设计了适用于多飞行器的SO(3)控制器实现对编队和姿态的协同控制.推力控制器用于调节无人机的位置与速度,并在此基础上构造旋转矩阵形式的姿态协同指令.文中相应设计了SO(3)姿态控制器用于实现指令跟踪,最后从理论上对协同稳定性进行了分析.提出的控制方法能够使得多四旋翼无人机形成期望的队形,并且保持姿态一致进行稳定飞行.仿真结果验证了本文方法的有效性.
