| 摘 要： | 提出了一种基于分段Lyapunov函数方法的带太阳帆板柔性卫星的姿态模糊控制方法。对于柔性卫星姿态动力学系统而言,强耦合、非线性以及较强的不确定性是其姿态系统的基本特征,本文针对这类被控对象,采用T-S模型作为万能逼近器,设计一种分段状态反馈控制方案。仿真结果表明,该方案可以保证卫星的姿态控制精度、结构振动抑制和控制系统鲁棒性。

| Abstract: | A fuzzy attitude control based on subsection Lyapunov method for flexible satellites with solar paddles was proposed. For flexible spacecraft is characteristics with strong coupling, nonlinearities and uncertainties, using T-S model as an approximation for the nonlinear system, a subsection state feedback control was designed. Simulation results show that the presented control can ensure the precision of the attitude control performance, suppression of the structure vibrations and robustness of the control system. |
