摘要
研究使用单框架控制力矩陀螺群 (SGCMGs)进行卫星姿态侧摆机动控制。研究频繁机动情况下由五棱锥构形和金字塔构形陀螺群进行侧摆机动控制的可行性 ,并探讨陀螺群构形奇异的避免问题。针对不同的陀螺群构形设计了不同的控制律 ,并比较两种构形的控制特性的异同。仿真结果验证了使用SGCMGs实现侧摆机动控制的有效性。
This paper deals with the problem of skew maneuver for an Earth observation satellite using single-gambal control moment gyros ( SGCMGs ). Both the five pyramid configuration (FPC) and the pyramid configuration (PC) are considered, whenever the SGCMGs carry on several times of maneuver in one orbital cycle. Two types of CMG's steering logics are developed for both FPC and PC , so that the SGCMGs can pass through, and also escape from singularities. Simulation results demonstrate the effectiveness of the proposed attitude control system.
