| 摘 要： | 对三轴稳定飞轮姿控小卫星的模糊控制方法进行了研究。不考虑解耦运算,基于模糊控制,以姿态角偏差及偏差变化率为输入,飞轮转动角加速度为输出,在每个通道分别加入模糊控制器,实现了对小卫星滚转、俯仰和偏航通道耦合系统的有效控制。仿真结果表明:该法对干扰抑制明显、对结构参数变化不敏感,响应过程有良好的快速性和较高的稳态精度(可达1×10-4rad),可避免传统方法中对动力学方程的直接解耦操作,应用时可将模糊控制规则转化为控制表储存在星载计算机,简单高效。

| Abstract: | The fuzzy control for small satellite of three-axis stabilization with flying wheel was studied in this paper.Based on fuzzy control,the control for the coupled system of rolling,pitching and yawing channel of the satellite was implemented when the angle deviation and the deviation rate was served as input,the acceleration of reaction-wheel was served as output and the fuzzy controller was put into each channel,in which the decouple-operation to the dynamics equation was avoided.The results showed that the ... |
