介绍一种直接由姿态误差四元数反馈和星体速率反馈所组成的姿态四元数反馈控制系统。通过四元数反馈增益阵的适当选择就能实现绕欧拉特征轴的转动。根据欧拉旋转定理,该转动提供了从任一起始方位到期望方位之间的最短角行程。
An attitude quaternion feedback control system composed of attitude error quaternion feedback and astral velocity feedback is introduced. The appropriate choice around the gain axis of the Euler can be achieved by quaternion feedback. According to Euler’s rotation theorem, this rotation provides the shortest angular travel from any starting position to the desired position.
