| 摘 要： | 将输入输出线性化控制与自适应模糊滑模控制相结合,并将其应用于挠性卫星姿态机动控制中.给出了卫星姿态控制器的基本形式.用自适应模糊控制逼近滑模控制中非线性控制分量,并推导了模糊规则参数调整的自适应律.在线调节自适应模糊控制器的参数以克服挠性卫星的不确定性,具有较强的鲁棒性.仿真结果表明该方法实现了较高精度的卫星姿态控制.

| Abstract: | The input-output linearization control is combined with the adaptive fuzzy sliding mode control,and is applied to the attitude maneuver control of the flexible satellite.Firstly,the basic control structure is presented.The adaptive fuzzy control is then utilized to approach the nonlinear control part of sliding mode control,and the adaptive law is also derived.Morever,the parameter of the adaptive fuzzy control is adjusted on-line to deal with the satellite uncertainty,thus the robustness of system is obtained.Finally,simulation results show that precise attitude control is accomplished in spite of the uncertainty in the system. |

| Keywords: | adaptive fuzzy control input-output linearization sliding mode control flexible satellite |
