本文对圆轨道上刚体卫星的姿态稳定问题给出了控制饱和效应的新结果。关于这个问题的大多数先前的结果已经解决了使用线性控制器来实现局部渐近稳定，本文提出的控制器，实现近全局渐近稳定。这是通过使用全球定义的模型来实现的，该模型结合了重力梯度效应和卫星相对于旋转的局部垂直局部水平坐标系的姿态的定义。李雅普诺夫方法用于分析闭环特性，但其应用考虑了切丛TSO（3）的几何形状，其上的全局动态演化。此外，所设计的控制律考虑了控制饱和效应
Control saturation effects new results are presented for the problem of attitude stabilization of a rigid satellite in a circular orbit. Most prior results on this problem have addressed use of linear controllers to achieve local asymptotic stability; this paper presents controllers that achieve near global asymptotic stability. This is accomplished by using globally defined models that incorporate gravity gradient effects and a definition of the attitude of the satellite with respect to the rotating local vertical local horizontal coordinate frame. Lyapunov methods are used to analyze the closed loop properties, but their application takes into account the geometry of the tangent bundle TSO(3) on which the global dynamics evolve. Furthermore, the designed control law accommodates control saturation effects
