【摘要】 综合轮控高精度优点和小卫星高集成度与姿态机动的要求，以反作用轮为执行机构，采用模型状态轨迹跟踪法，在反作用轮速率饱和约束条件下，进行了模型状态轨迹和基于模型状态轨迹控制律的设计。此外，还针对飞轮摩擦等带来的常值干扰，对控制律进行了修正，以提高控制精度。仿真结果表明，此控制方法能较好地实现小卫星姿态的大角度机动。更多还原

【Abstract】 In this paper,model status trace method is adopted to plan model status trace and to design this trace contoller based on reaction wheels for small satellites’ integration and attitude slew,which is with the consideration of reaction wheels’ rate saturation.In addition,the control law has been modified to preclude the influence of reaction wheels’ friction.Simulation results prove that the control method is effective to accomplish small satellites’ large angle rotation.更多还原
